+			AnimationActions 用来调度存储在[page:AnimationClip AnimationClips]中的动画。<br /><br />
+
+			说明: AnimationAction的大多数方法都可以链式调用<br /><br />
+
+			在使用手册的“下一步”章节中，“动画系统”一文对three.js动画系统中的不同元素作出了概述。
+		</p>
+
+
+		<h2>构造器</h2>
+
+
+		<h3>[name]( [param:AnimationMixer mixer], [param:AnimationClip clip], [param:Object3D localRoot] )</h3>
+		<p>
+			[page:AnimationMixer mixer] - 被此动作控制的 *动画混合器* <br />
+			[page:AnimationClip clip] - *动画剪辑* 保存了此动作当中的动画数据 <br />
+			[page:Object3D localRoot] - 动作执行的根对象 <br /><br />
+
+			说明: 不要直接调用这个构造函数，而应该先用[page:AnimationMixer.clipAction]实例化一个AnimationAction，因为这个方法提供了缓存以提高性能。
+		</p>
+
+
+		<h2>属性</h2>
+
+
+		<h3>[property:Boolean clampWhenFinished]</h3>
+		<p>
+			如果 *clampWhenFinished* 值设为true, 那么动画将在最后一帧之后自动暂停（[page:.paused paused]）<br /><br />
+
+			如果 *clampWhenFinished* 值为false, [page:.enabled enabled] 属性值将在动作的最后一次循环完成之后自动改为false, 那么这个动作以后就不会再执行。 <br /><br />
+
+			默认值为false <br /><br />
+
+			说明: 动作如果被中断了，*clampWhenFinished*将无效 (只有当最后一次循环执行完毕之后才能起效）
+		</p>
+
+		<h3>[property:Boolean enabled]</h3>
+		<p>
+			*enabled* 值设为*false*会禁用动作, 也就是无效.默认值是*true* <br /><br />
+
+			当*enabled*被重新置为*true*, 动画将从当前时间（[page:.time time]）继续
+			(将 *enabled* 置为 *false* 不会重置此次动作) <br /><br />
+
+			说明: 将*enabled*置为*true*不会让动画自动重新开始。只有满足以下条件时才会马上重新开始:
+            暂停（[page:.paused paused]）值为*false*, 同时动作没有失效 (执行停止([page:.stop stop])命令或重置([page:.reset reset])命令，
+            且权重([page:.weight weight])和时间比例([page:.timeScale timeScale])都不能为0
+
+		</p>
+
+		<h3>[property:Number loop]</h3>
+		<p>
+			循环模式 (可以通过[page:.setLoop setLoop]改变)。默认值是
+			[page:Animation THREE.LoopRepeat] (重复[page:.repetitions repetitions]次数无穷)<br /><br />
+
+		    必须是以下值之一：<br /><br />
+			[page:Animation THREE.LoopOnce] - 只执行一次 <br />
+			[page:Animation THREE.LoopRepeat] - 重复次数为*repetitions*的值, 且每次循环结束时候将回到起始动作开始下一次循环。 <br />
+			[page:Animation THREE.LoopPingPong] - 重复次数为*repetitions*的值, 且像乒乓球一样在起始点与结束点之间来回循环。
+		</p>
+
+		<h3>[property:Boolean paused]</h3>
+		<p>
+			*paused*置为*true*会通过将动作的有效时间比例改为0来使动作暂停执行。默认值是*false*<br /><br />
+		</p>
+
+		<h3>[property:Number repetitions]</h3>
+		<p>
+			整个动作过程动画剪辑（[page:AnimationClip]）执行的次数，可以通过[page:.setLoop setLoop]修改。默认值是*Infinity*<br /><br />
+			如果循环模式（[page:.loop loop mode]）值被设置为[page:Animation THREE.LoopOnce]，repetitions值将会无效。
+
+		</p>
+
+		<h3>[property:Number time]</h3>
+		<p>
+			动作开始的时间点 (单位是秒, 从0开始计时).<br /><br />
+
+			这个值被限定在 0到clip.duration(根据循环状态)范围之内. 可以通过改变时间比例（[page:.timeScale timeScale]) (使用
+			[page:.setEffectiveTimeScale setEffectiveTimeScale] 或者 [page:.setDuration setDuration])来将它相对于全局的混合器缩放.<br />
+		</p>
+
+		<h3>[property:Number timeScale]</h3>
+		<p>
+			时间([page:.time time])的比例因子. 值为0时会使动画暂停。值为负数时动画会反向执行。默认值是1。<br /><br />
+			关于*timeScale*属性/方法 (不同于 *time*) 有:
+			[page:.getEffectiveTimeScale getEffectiveTimeScale],
+			[page:.halt halt],
+			[page:.paused paused],
+			[page:.setDuration setDuration],
+			[page:.setEffectiveTimeScale setEffectiveTimeScale],
+			[page:.stopWarping stopWarping],
+			[page:.syncWith syncWith],
+			[page:.warp warp].
+		</p>
+
+		<h3>[property:Number weight]</h3>
+		<p>
+			动作的影响程度 (取值范围[0, 1]). 0 (无影响)到1（完全影响）之间的值可以用来混合多个动作。默认值是1<br /><br />
+			关于*weight*的属性/方法有:
+			[page:.crossFadeFrom crossFadeFrom],
+			[page:.crossFadeTo crossFadeTo],
+			[page:.enabled enabled],
+			[page:.fadeIn fadeIn],
+			[page:.fadeOut fadeOut],
+			[page:.getEffectiveWeight getEffectiveWeight],
+			[page:.setEffectiveWeight setEffectiveWeight],
+			[page:.stopFading stopFading].
+		</p>
+
+		<h3>[property:Boolean zeroSlopeAtEnd]</h3>
+		<p>
+            启用平滑插值，无须单独剪辑开始、循环和结束。默认值是*true*
+		</p>
+
+		<h3>[property:Boolean zeroSlopeAtStart]</h3>
+		<p>
+            启用平滑插值，无须单独剪辑开始、循环和结束。默认值是*true*
+		</p>
+
+
+		<h2>方法</h2>
+
+
+		<h3>[method:AnimationAction crossFadeFrom]( [param:AnimationAction fadeOutAction], [param:Number durationInSeconds], [param:Boolean warpBoolean] )</h3>
+		<p>
+			在传入的时间段内，让此动作淡入([page:.fadeIn fade in]),同时让另一个动作淡出。此方法可链式调用。<br /><br />
+
+			如果warpBoolean值是true, 额外的 [page:.warp warping] (时间比例的渐变)将会被应用。 <br /><br />
+
+			说明: 与 *fadeIn*/*fadeOut*一样, 淡入淡出动作开始/结束时的权重是1.
+
+		</p>
+
+		<h3>[method:AnimationAction crossFadeTo]( [param:AnimationAction fadeInAction], [param:Number durationInSeconds], [param:Boolean warpBoolean] )</h3>
+		<p>
+            在传入的时间段内, 让此动作淡出（[page:.fadeOut fade out]），同时让另一个动作淡入。此方法可链式调用。<br /><br />
+			如果warpBoolean值是true, 额外的 [page:.warp warping] (时间比例的渐变)将会被应用。<br /><br />
+
+			说明: 与 *fadeIn*/*fadeOut*一样, 淡入淡出动作开始/结束时的权重是1.
+		</p>
+
+		<h3>[method:AnimationAction fadeIn]( [param:Number durationInSeconds] )</h3>
+		<p>
+            在传入的时间间隔内，逐渐将此动作的权重（[page:.weight weight]）由0升到1。此方法可链式调用。
+		</p>
+
+		<h3>[method:AnimationAction fadeOut]( [param:Number durationInSeconds] )</h3>
+		<p>
+            在传入的时间间隔内，逐渐将此动作的权重（[page:.weight weight]）由1降至0。此方法可链式调用。
+		</p>
+
+		<h3>[method:Number getEffectiveTimeScale]()</h3>
+		<p>
+			返回有效时间比例(考虑当前的变形状态和[page:.paused paused]值).
+		</p>
+
+		<h3>[method:number getEffectiveWeight]()</h3>
+		<p>
+			返回影响权重(考虑当前淡入淡出状态和[page:.enabled enabled]的值).
+		</p>
+
+		<h3>[method:AnimationClip getClip]()</h3>
+		<p>
+			返回存有此动作的动画数据的剪辑
+		</p>
+
+		<h3>[method:AnimationMixer getMixer]()</h3>
+		<p>
+            返回负责完成此动作的混合器
+		</p>
+
+		<h3>[method:Object3D getRoot]()</h3>
+		<p>
+			返回执行此动作的根对象
+		</p>
+
+		<h3>[method:AnimationAction halt]( [param:Number durationInSeconds] )</h3>
+		<p>
+			在传入的时间间隔内，通过从当前值开始逐渐降低时间比例([page:.timeScale timeScale])使动画逐渐减速至0。此方法可链式调用。
+		</p>
+
+		<h3>[method:Boolean isRunning]()</h3>
+		<p>
+			返回当前此动作的时间([page:.time time])是否正在流逝 <br /><br />
+
+			除了在混合器中被激活之外 (参见[page:.isScheduled isScheduled])必须满足以下条件才会返回true:
+			[page:.paused paused]值等于false, [page:.enabled enabled]值为true,
+			[page:.timeScale timeScale]值不为0, 而且没有安排延时启动([page:.startAt startAt]).<br /><br />
+
+			说明 *isRunning* 为true并不意味着此动画一定会切实地被看到。仅当权重([page:.weight weight])被设置为非零值时才是这种情况。
+		</p>
+
+		<h3>[method:Boolean isScheduled]()</h3>
+		<p>
+			如果动作是在混合器中被激活的，返回true。<br /><br />
+			说明: 这并不意味着动画正在执行中 (需要额外判断[page:.isRunning isRunning]值)
+		</p>
+
+		<h3>[method:AnimationAction play]()</h3>
+		<p>
+			让混合器激活动作。此方法可链式调用。<br /><br />
+
+			说明: 激活动作并不意味着动画会立刻开始: 如果动作在此之前已经完成（到达最后一次循环的结尾），或者如果已经设置了延时
+			启动(通过 [page:.startAt startAt])，则必须先执行重置操作（[page:.reset reset]）。 一些其它的设置项 ([page:.paused paused]=true, [page:.enabled enabled]=false,
+			[page:.weight weight]=0, [page:.timeScale timeScale]=0) 也可以阻止动画的开始。
+		</p>
+
+		<h3>[method:AnimationAction reset]()</h3>
+		<p>
+			重置动作。此方法可链式调用。<br /><br />
+
+			该方法会将暂停值 [page:.paused paused] 设为false, 启用值[page:.enabled enabled] 设为true,时间值
+			[page:.time time]设为0, 中断任何预定的淡入淡出和变形, 以及移除内部循环次数以及延迟启动。<br /><br />
+
+			说明: 停止方法[page:.stop stop]内调用了重置方法（reset）, 但是 .*reset*不会调用 .*stop*。
+            这就表示: 如果你想要这两者, 重置并且停止, 不要调用*reset*; 而应该调用*stop*。
+		</p>
+
+		<h3>[method:AnimationAction setDuration]( [param:Number durationInSeconds] )</h3>
+		<p>
+			设置单此循环的持续时间(通过调整时间比例（[page:.timeScale timeScale]）以及停用所有的变形)。此方法可以链式调用。
+		</p>
+
+		<h3>[method:AnimationAction setEffectiveTimeScale]( [param:Number timeScale] )</h3>
+		<p>
+			设置时间比例（[page:.timeScale timeScale]）以及停用所有的变形)。 此方法可以链式调用。<br /><br />
+
+			如果暂停 （[page:.paused paused]）值为false, 有效的时间比例(一个内部属性) 也会被设为该值; 否则有效时间比例 (直接影响当前动画
+			将会被设为0.<br /><br />
+
+			说明: 如果时间比例.*timeScale* 被此方法设为0，暂停值*paused*不会被自动改为*true*。
+		</p>
+
+		<h3>[method:AnimationAction setEffectiveWeight]( [param:Number weight] )</h3>
+		<p>
+			设置权重（[page:.weight weight]）以及停止所有淡入淡出。该方法可以链式调用。<br /><br />
+
+			如果启用属性（[page:.enabled enabled]）为true, 那么有效权重(一个内部属性) 也会被设为该值; 否则有效权重 (直接影响当前动画)将会被设为0.<br /><br />
+
+			说明: 如果该方法将权重*weight*值设为0，启用值*enabled*不会被自动改为*false*。
+		</p>
+
+		<h3>[method:AnimationAction setLoop]( [param:Number loopMode], [param:Number repetitions] )</h3>
+		<p>
+			设置循环（[page:.loop loop mode]）及循环重复次数（[page:.repetitions repetitions]）。改方法可被链式调用。
+		</p>
+
+		<h3>[method:AnimationAction startAt]( [param:Number startTimeInSeconds] )</h3>
+		<p>
+			定义延时启动的事件 (通常会传入[page:AnimationMixer.time] +
+			deltaTimeInSeconds)。 该方法可以链式调用。<br /><br />
+
+			说明: 如果 *startAt*方法是和[page:.play play]方法一起链式调用, 或者动画已经在混合器中被激活 (通过先行调用*play*, 同时没有停止或重置)，动画将仅在给定时间开始.
+		</p>
+
+		<h3>[method:AnimationAction stop]()</h3>
+		<p>
+			让混合器停止动作。该方法可以被链式调用。<br /><br />
+
+			动作会马上停止以及完全[page:.reset 重置].<br /><br />
+
+			说明: 你可以通过[page:AnimationMixer.stopAllAction mixer.stopAllAction]在一个混合器中一举停止所有处于激活态的动作。
+		</p>
+
+		<h3>[method:AnimationAction stopFading]()</h3>
+		<p>
+			停止动作中所有预定的淡入淡出（[page:.fadeIn fading]）。该方法可以被链式调用。
+		</p>
+
+		<h3>[method:AnimationAction stopWarping]()</h3>
+		<p>
+			停用动作中所有预定的变形[page:.warp warping]。该方法可被链式调用。
+		</p>
+
+		<h3>[method:AnimationAction syncWith]( [param:AnimationAction otherAction] )</h3>
+		<p>
+			将此动作与传入的其它动作同步。此方法可被链式调用。<br /><br />
+
+			同步是通过将动作的时间([page:.time time])或时间比例([page:.timeScale timeScale])与另一动作设置一致来实现的
+			(停用所有预定的变形)。<br /><br />
+
+			说明: 另一动作的 *time* 和 *timeScale*未来变化将不会被检测到.
+		</p>
+
+		<h3>[method:AnimationAction warp]( [param:Number startTimeScale], [param:Number endTimeScale], [param:Number durationInSeconds] )</h3>
+		<p>
+            在传入的事件间隔内，通过逐渐将时间比例[page:.timeScale timeScale]由*startTimeScale*修改至*endTimeScale*来改变回放速度。该方法可被链式调用。
+		</p>
+
+
+		<h2>事件</h2>
+
+
+		<p class="desc">
+			有两个事件分别表示了单次循环的结束和全部动作的结束，你可以这样对它们做出响应:

+
+		<p>
+            和[link:https://github.com/mrdoob/three.js/wiki/JSON-Model-format-3 JSON model format]的动画层级相反，
+            关键帧轨道（KeyframeTrack）不会将单帧作为对象存储在“key”数组(一个存有每一帧的时间和值的地方)中。
+
+		</p>
+
+		<p>
+            关键帧轨道(KeyframeTrack)中总是存在两个数组：[page:.times times]数组按顺序存储该轨道的所有关键帧的时间值，而[page:.values values]数组包含动画属性的相应更改值。
+		</p>
+
+		<p>
+            值数组中的每一个成员，属于某一特定时间点，不仅可以是一个简单的数字，还可以是（比如）一个向量（如果是位置动画）或者是一个四元数（如果是旋转动画）。
+            因此，值数组（也是一个平面阵列）的长度可能是时间数组的三四倍。
+		</p>
+
+		<p>
+            与不同类型的动画值对应，存在若干关键帧轨道(KeyframeTrack)的子类，继承了它大多数属性和方法：

+		</p>
+
+		<p>
+            由于显式值仅针对存储在时间数组中的离散时间点指定，因此必须在两个时间点之间进行插值
+		</p>
+
+		<p>
+            轨道的名称对于这个轨道与动画节点的特定属性的连接(由[page:PropertyBinding]完成)很重要。

+		<h2>构造器</h2>

+		<h3>[name]( [param:String name], [param:Array times], [param:Array values], [param:Constant interpolation] )</h3>

+		</p>
+
+
+		<h2>属性</h2>
+
+
+		<h3>[property:String name]</h3>
+		<p>
+            轨道的名称可以指动画对象中的变形目标([page:Geometry.morphTargets morph targets])、骨骼([page:SkinnedMesh bones])或可能的其他值
+			查看[page:PropertyBinding.parseTrackName]可获知哪些形式的字符串可以解析出绑定的属性:
+		</p>
+		<p>
+            可以使用节点名称或uuid（尽管它需要位于传递到混合器的场景图节点的子树中）引用到某节点。或者， 如果轨道名称的首字符是点,
+			该轨道会应用到传入到混合器的根节点上。
+		</p>
+
+		<p>
+			通常，在该节点之后会直接指定一个属性。 但是也可以再指定一个子属性， 例如 如果只是想通过浮动轨道使X组件旋转，可使用 .rotation[x]。
+		</p>
+
+		<p>
+            还可以使用对象名称来指定骨骼或多材质，例如：.bones[R_hand].scale；再比如，材料数组中的第四个材料的漫反射颜色的红通道可以通过 .materials[3].diffuse[r]访问到。
+		</p>
+
+		<p>
+			属性绑定也会解析变形目标名称, 例如: .morphTargetInfluences[run]
+		</p>
+
+		<p>
+			说明: 轨道名称不一定得唯一。 多个轨道可驱动统一属性， 此时结果应该基于多个轨道之间根据其各自动作的权重的加权混合。

+			[page:Geometry]的时候，改变这个值不会有任何效果。
+<br /><br />
+
+
+
+		</p>
+
+
+		<h2>绘图模式</h2>
+
+		<code>
+			THREE.TrianglesDrawMode
+		</code>
+		<p>
+			这是默认值，这将使得每三个连续顶点(v0, v1, v2)，(v2, v3, v5)，……被解释为一个单独的三角形。
+			<br />
+			如果顶点的数量不是3的倍数，那么将会忽略多余的顶点。
+		</p>
+
+		<code>
+			THREE.TriangleStripDrawMode
+		</code>
+		<p>
+			这将使得一系列的三角形（由(v0, v1, v2)，(v2, v1, v3)，(v2, v3, v4)，……给定）一个一个地连在一起，每一个连续的三角形将和前一个三角形共享两个顶点。
+		</p>
+

+		<p>
+这将会使得一个序列中的每一个三角形（由(v0, v1, v2)，(v0, v2, v3)，(v0, v3, v4)，……给定）共享它们的第一个顶点（就像风扇一样）。<br /><br />
+
+			<em>注意：</em>截至[link:https://en.wikipedia.org/wiki/DirectX#DirectX_10 DirectX10]这个模式还没有被支持。
+			由于Chorme和Firefox在Windows上是使用[link:https://en.wikipedia.org/wiki/ANGLE_(software) ANGLE]来渲染WebGL的，所以这种模式将会在内部转换为受支持的模式，

+		<h1>[name]</h1>
+
+		<p class="desc">
+		This class stores data for an attribute (such as vertex positions, face indices, normals,
+		colors, UVs, and any custom attributes ) associated with a [page:BufferGeometry], which allows
+		for more efficient passing of data to the GPU. See that page for details and a usage example.<br /><br />
+
+		Data is stored as vectors of any length (defined by [page:BufferAttribute.itemSize itemSize]),
+		and in general in the methods outlined below if passing in an index, this is automatically
+		multiplied by the vector length.
+		</p>
+
+		<h2>Constructor</h2>
+		<h3>[name]( [param:TypedArray array], [param:Integer itemSize], [param:Boolean normalized] )</h3>
+		<p>
+		[page:TypedArray array] -- Must be a [link:https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/TypedArray TypedArray].
+		Used to instantiate the buffer. <br />
+		This array should have
+	 	<code>itemSize * numVertices</code>
+		elements, where numVertices is the number of vertices in the associated [page:BufferGeometry BufferGeometry].<br /><br />
+
+
+		[page:Integer itemSize] --  the number of values of the array that should be associated with
+		a particular vertex. For instance, if this
+		attribute is storing a 3-component vector (such as a position, normal, or color), then itemSize should be 3.
+		<br /><br />
+
+		[page:Boolean normalized] -- (optional) Indicates how the underlying data in the buffer maps
+		to the values in the GLSL code. For instance, if [page:TypedArray array] is an instance of
+		UInt16Array, and [page:Boolean normalized] is true, the values 0 - +65535 in the array
+		 data will be mapped to 0.0f - +1.0f in the GLSL attribute. An Int16Array (signed) would map
+		 from -32767 - +32767  to -1.0f - +1.0f. If [page:Boolean normalized] is false, the values
+		 will be converted to floats which contain the exact value, i.e. 32767 becomes 32767.0f.
+		</p>
+
+		<h2>Properties</h2>
+
+		<h3>[property:TypedArray array]</h3>
+		<p>
+		The [page:TypedArray array] holding data stored in the buffer.
+		</p>
+
+		<h3>[property:Integer count]</h3>
+		<p>
+		Stores the [page:BufferAttribute.array array]'s length divided by the [page:BufferAttribute.itemSize itemSize].<br /><br />
+
+		If the buffer is storing a 3-component vector (such as a position, normal, or color),
+		then this will count the number of such vectors stored.
+		</p>
+
+		<h3>[property:Boolean dynamic]</h3>
+		<p>
+			Whether the buffer is dynamic or not. Default is *false*.<br />
+
+			If false, the GPU is informed that contents of the buffer are likely to be used often and not change often.
+			This corresponds to the  [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/bufferData gl.STATIC_DRAW] flag.<br />
+			if true, the GPU is informed that contents of the buffer are likely to be used often and change often.
+			This corresponds to the  [link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/bufferData gl.DYNAMIC_DRAW] flag.
+		</p>
+
+		<h3>[property:Boolean isBufferAttribute]</h3>
+		<p>
+			Used to check whether this or derived classes are BufferAttributes. Default is *true*.<br /><br />
+
+			You should not change this, as it used internally for optimisation.
+		</p>
+
+		<h3>[property:Integer itemSize]</h3>
+		<p>The length of vectors that are being stored in the [page:BufferAttribute.array array].</p>
+
+		<h3>[property:String name]</h3>
+		<p>

+
+		<h3>[property:Boolean needsUpdate]</h3>
+		<p>
+		Flag to indicate that this attribute has changed and should be re-sent to the GPU.
+		Set this to true when you modify the value of the array.<br /><br />
+
+		Setting this to true also increments the [page:BufferAttribute.version version].
+		</p>
+
+		<h3>[property:Boolean normalized]</h3>
+		<p>
+		Indicates how the underlying data in the buffer maps to the values in the GLSL shader code.
+		See the constructor above for details.
+		</p>
+
+		<h3>[property:Function onUploadCallback]</h3>
+		<p>
+		A callback function that is executed after the Renderer has transfered the attribute array data to the GPU.
+		</p>
+
+		<h3>[property:Object updateRange]</h3>
+		<p>Object containing:<br />
+			[page:Integer offset]: Default is *0*. Position at whcih to start update.<br />
+			[page:Integer count]: Default is *-1*, which means don't use update ranges. <br /><br />
+
+			This can be used to only update some components of stored vectors (for example, just the component
+			related to color).
+		</p>
+
+		<h3>[property:Integer version]</h3>
+		<p>A version number, incremented every time the [page:BufferAttribute.needsUpdate needsUpdate] property is set to true.</p>

+		<h1>[name]</h1>
+
+		<p>
+		An efficient representation of mesh, line, or point geometry. Includes vertex positions, face
+		indices, normals, colors, UVs, and custom attributes within buffers, reducing the cost of
+		passing all this data to the GPU.
+		</p>
+		<p>
+		To read and edit data in BufferGeometry attributes, see [page:BufferAttribute] documentation.
+		</p>
+		<p>
+		For a less efficient but easier-to-use representation of geometry, see [page:Geometry].
+		</p>
+
+		<h2>Example</h2>
+		<code>
+		var geometry = new THREE.BufferGeometry();
+		// create a simple square shape. We duplicate the top left and bottom right
+		// vertices because each vertex needs to appear once per triangle.
+		var vertices = new Float32Array( [

+
+		<h2>Accessing Attributes</h2>
+		<p>
+		WebGL stores data associated with individual vertices of a geometry in <em>attributes</em>.
+		Examples include the position of the vertex, the normal vector for the vertex, the vertex color,
+		and so on. When using [page:Geometry], the [page:WebGLRenderer renderer] takes care of wrapping
+		up this information into typed array buffers and sending this data to the shader. With
+		BufferGeometry, all of this data is stored in buffers associated with individual attributes.
+		This means that to get the position data associated with a vertex (for instance), you must call
+		[page:.getAttribute] to access the 'position' [page:BufferAttribute attribute], then access the individual
+		x, y, and z coordinates of the position.
+		</p>
+		<p>
+		The following attributes are set by various members of this class:
+		</p>
+		<h3>[page:BufferAttribute position] (itemSize: 3)</h3>
+		<p>
+		Stores the x, y, and z coordinates of each vertex in this geometry. Set by [page:.fromGeometry]().
+		</p>
+
+		<h3>[page:BufferAttribute normal] (itemSize: 3)</h3>
+		<p>
+		Stores the x, y, and z components of the vertex normal vector of each vertex in this geometry.
+		Set by [page:.fromGeometry]().
+		</p>
+
+		<h3>[page:BufferAttribute color] (itemSize: 3)</h3>
+		<p>
+		Stores the red, green, and blue channels of vertex color of each vertex in this geometry.
+		Set by [page:.fromGeometry]().
+		</p>
+
+		<p>
+		In addition to the the built-in attributes, you can set your own custom attributes using the addAttribute method. With [page:Geometry], these attributes are set and stored on the [page:Material]. In BufferGeometry, the attributes are stored with the geometry itself. Note that you still need to set the attributes information on the material as well, but the value of each attribute is stored in the BufferGeometry.
+		</p>
+
+
+		<h2>Constructor</h2>
+
+
+		<h3>[name]()</h3>
+		<div>
+		This creates a new [name]. It also sets several properties to a default value.
+		</div>
+
+
+		<h2>Properties</h2>
+
+		<h3>[property:Object attributes]</h3>
+		<p>
+		This hashmap has as id the name of the attribute to be set and as value the [page:BufferAttribute buffer] to set it to.
+		Rather than accessing this property directly, use [page:.addAttribute] and [page:.getAttribute] to access attributes of this geometry.
+		</p>
+
+		<h3>[property:Box3 boundingBox]</h3>
+		<p>
+			Bounding box for the bufferGeometry, which can be calculated with
+			[page:.computeBoundingBox](). Default is *null*.
+		</p>
+
+		<h3>[property:Sphere boundingSphere]</h3>
+		<p>
+			Bounding sphere for the bufferGeometry, which can be calculated with
+			[page:.computeBoundingSphere](). Default is *null*.
+		</p>
+
+		<h3>[property:Object drawRange]</h3>
+		<p>
+			Used to determine what part of the geometry should be rendered. This should not
+			be set directly, instead use [page:.setDrawRange].<br />
+			Default is
+			<code>
+				{ start: 0, count: Infinity }
+			</code>
+		</p>
+
+		<h3>[property:Array groups]</h3>
+		<p>
+			Split the geometry into groups, each of which will be rendered in a separate WebGL draw call.
+			This allows an array of materials to be used with the bufferGeometry.<br /><br />
+
+			Each group is an object of the form:
+			<code>{ start: Integer, count: Integer, materialIndex: Integer }</code>
+			where start specifies the first element in this draw call – the first vertex for non-indexed geometry,
+			otherwise the first triangle index. Count specifies how many vertices (or indices) are included, and
+			materialIndex specifies the material array index to use.<br /><br />
+
+			Use [page:.addGroup] to add groups, rather than modifying this array directly.
+		</p>
+
+
+		<!-- Note: groups used to be called drawCalls
+
+		<h3>[property:Array drawcalls]</h3>
+		<p>
+		For geometries that use indexed triangles, this Array can be used to split the object
+		into multiple WebGL draw calls. Each draw call will draw some subset of the vertices
+		in this geometry using the configured [page:Material shader]. This may be necessary if,
+		for instance, you have more than 65535 vertices in your object.
+		</p> -->
+
+
+		<h3>[property:Integer id]</h3>
+		<p>Unique number for this bufferGeometry instance.</p>
+
+		<h3>[property:BufferAttribute index]</h3>
+		<p>
+			Allows for vertices to be re-used across multiple triangles; this is called using "indexed triangles" and
+			works much the same as it does in [page:Geometry]: each triangle is associated with the indices of three vertices.
+			This attribute therefore stores the index of each vertex for each triangular face.
+
+			If this attribute is not set, the [page:WebGLRenderer renderer] assumes that each three contiguous
+			positions represent a single triangle.
+
+			Default is *null*.
+		</p>
+
+		<h3>[property:Boolean isBufferGeometry]</h3>
+		<p>
+			Used to check whether this or derived classes are BufferGeometries. Default is *true*.<br /><br />
+
+			You should not change this, as it used internally for optimisation.
+		</p>
+
+		<h3>[property:Object morphAttributes]</h3>
+		<p>
+			Hashmap of [page:BufferAttribute]s holding details of the geometry's [page:Geometry.morphTargets morphTargets].
+		</p>
+
+		<h3>[property:String name]</h3>

+		</p>
+
+		<h3>[property:Object userData]</h3>
+		<p>
+		An object that can be used to store custom data about the BufferGeometry. It should not hold
+		references to functions as these will not be cloned.
+		</p>
+
+		<h3>[property:String uuid]</h3>
+		<p>
+		[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance.
+		This gets automatically assigned and shouldn't be edited.
+		</p>
+
+		<h2>Methods</h2>
+
+		<h3>[page:EventDispatcher EventDispatcher] methods are available on this class.</h3>
+
+		<h3>[method:BufferGeometry addAttribute]( [param:String name], [param:BufferAttribute attribute] )</h3>
+		<p>
+		Adds an attribute to this geometry. Use this rather than the attributes property,
+		because an internal hashmap of [page:.attributes] is maintained to speed up iterating over
+		attributes.
+		</p>
+
+		<h3>[method:null addGroup]( [param:Integer start], [param:Integer count], [param:Integer materialIndex] )</h3>
+		<p>

+
+		<h3>[method:null computeBoundingSphere]()</h3>
+		<p>
+		Computes bounding sphere of the geometry, updating [page:.boundingSphere] attribute.<br />

+		<h2>Properties</h2>
+
+		<h3>[property:Box3 boundingBox]</h3>
+		<p>
+			Bounding box for the Geometry, which can be calculated with
+			[page:.computeBoundingBox](). Default is *null*.
+		</p>
+
+		<h3>[property:Sphere boundingSphere]</h3>
+		<p>
+			Bounding sphere for the Geometry, which can be calculated with

+		</p>
+
+		<h3>[property:Array colors]</h3>
+		<p>
+		Array of vertex [page:Color colors], matching number and order of vertices.<br /><br />
+
+		This is used by [page:Points] and [page:Line] and any classes derived from those such as [page:LineSegments] and various helpers.
+		[page:Mesh Meshes] use [page:Face3.vertexColors] instead of this.<br /><br />
+
+		To signal an update in this array, [page:Geometry Geometry.colorsNeedUpdate] needs to be set to true.
+		</p>
+
+		<h3>[property:Array faces]</h3>
+		<p>
+		Array of [page:Face3 faces].<br />
+		The array of faces describe how each vertex in the model is connected to form faces.
+		Additionally it holds information about face and vertex normals and colors.<br /><br />
+		To signal an update in this array, [page:Geometry Geometry.elementsNeedUpdate] needs to be set to true.
+		</p>
+
+		<h3>[property:Array faceVertexUvs]</h3>
+		<p>
+		Array of face [link:https://en.wikipedia.org/wiki/UV_mapping UV] layers, used for mapping textures onto the geometry.<br />
+		Each UV layer is an array of [page:UV]s matching the order and number of vertices in faces.<br /><br />
+		To signal an update in this array, [page:Geometry Geometry.uvsNeedUpdate] needs to be set to true.
+		</p>
+
+		<h3>[property:Integer id]</h3>
+		<p>Unique number for this geometry instance.</p>
+
+		<h3>[property:Boolean isGeometry]</h3>
+		<p>
+			Used to check whether this or derived classes are Geometries. Default is *true*.<br /><br />
+
+			You should not change this, as it used internally for optimisation.
+		</p>
+
+		<h3>[property:array lineDistances]</h3>
+		<p>
+		An array containing distances between vertices for Line geometries.
+		This is required for [page:LineDashedMaterial] to render correctly.
+		</p>
+
+		<h3>[property:Array morphTargets]</h3>
+		<p>
+		Array of [link:https://en.wikipedia.org/wiki/Morph_target_animation morph targets]. Each morph target is a Javascript object:
+		<code>{ name: "targetName", vertices: [ new THREE.Vector3(), ... ] }</code>
+		Morph vertices match number and order of primary vertices.
+		</p>
+
+		<h3>[property:Array morphNormals]</h3>
+		<p>
+		Array of morph normals. Morph normals have similar structure as morph targets, each normal set is a Javascript object:
+		<code>morphNormal = { name: "NormalName", normals: [ new THREE.Vector3(), ... ] }</code>
+
+		See the [example:webgl_morphnormals WebGL / morphNormals] example.
+		</p>
+
+		<h3>[property:String name]</h3>
+		<p>Optional name for this geometry. Default is an empty string.</p>
+
+		<h3>[property:Array skinWeights]</h3>
+		<p>
+		When working with a [page:SkinnedMesh], each vertex can have up to 4 [page:Bone bones] affecting it.
+		The skinWeights property is an array of weight values that correspond to the order of the vertices in
+		the geometry. So for instance, the first skinWeight would correspond to the first vertex in the geometry.
+		Since each vertex can be modified by 4 bones, a [page:Vector4] is used to represent the skin weights
+		for that vertex.
+		</p>
+		<p>
+		The values of the vector should typically be between 0 and 1. For instance when set to 0 the bone
+		transformation will have no affect. When set to 0.5 it will have 50% affect. When set to 100%, it will
+		have 100% affect. If there is only 1 bone associated with the vertex then you only need to worry about
+		the first component of the vector, the rest can be ignored and set to 0.
+		</p>
+
+		<h3>[property:Array skinIndices]</h3>
+		<p>
+		Just like the skinWeights property, the skinIndices' values correspond to the geometry's vertices.
+		Each vertex can have up to 4 bones associated with it. So if you look at the first vertex, and the
+		first skinIndex, this will tell you the bones associated with that vertex. For example the first vertex
+		could have a value of <strong>( 10.05, 30.10, 12.12 )</strong>. Then the first skin index could have the
+		value of <strong>( 10, 2, 0, 0 )</strong>. The first skin weight could have the value of
+		<strong>( 0.8, 0.2, 0, 0 )</strong>. In affect this would take the first vertex, and then the bone
+		<strong>mesh.bones[10]</strong> and apply it 80% of the way. Then it would take the bone <strong>skeleton.bones[2]</strong>
+		and apply it 20% of the way. The next two values have a weight of 0, so they would have no affect.
+		</p>
+		<p>
+		In code another example could look like this:
+		<code>
+		// e.g.
+		geometry.skinIndices[15] = new THREE.Vector4(   0,   5,   9, 10 );
+		geometry.skinWeights[15] = new THREE.Vector4( 0.2, 0.5, 0.3,  0 );
+
+		// corresponds with the following vertex
+		geometry.vertices[15];
+
+		// these bones will be used like so:
+		skeleton.bones[0]; // weight of 0.2
+		skeleton.bones[5]; // weight of 0.5
+		skeleton.bones[9]; // weight of 0.3
+		skeleton.bones[10]; // weight of 0
+		</code>
+		</p>
+
+		<h3>[property:String uuid]</h3>
+		<p>
+		[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance.
+		This gets automatically assigned and shouldn't be edited.
+		</p>
+
+		<h3>[property:Array vertices]</h3>
+		<p>
+		Array of [page:Vector3 vertices].<br />
+		The array of vertices holds the position of every vertex in the model.<br />
+		To signal an update in this array, [page:.verticesNeedUpdate] needs to be set to true.
+		</p>

+
+		<h3>[property:Boolean normalsNeedUpdate]</h3>
+		<p>Set to *true* if the normals array has been updated.</p>

+		<p>Array with object's children. See [page:Group] for info on manually grouping objects.</p>
+
+		<h3>[property:Boolean frustumCulled]</h3>
+		<p>
+		When this is set, it checks every frame if the object is in the frustum of the camera before rendering the object.
+		Otherwise the object gets rendered every frame even if it isn't visible. Default is *true*.

+
+		<h3>[property:Layers layers]</h3>
+		<p>
+		The layer membership of the object. The object is only visible if it has at least one
+		layer in common with the [page:Camera] in use.
+		</p>
+
+		<h3>[property:Matrix4 matrix]</h3>
+		<p>The local transform matrix.</p>
+
+		<h3>[property:Boolean matrixAutoUpdate]</h3>
+		<p>
+		When this is set, it calculates the matrix of position, (rotation or quaternion) and

+		<h3>[property:Matrix4 matrixWorld]</h3>
+		<p>
+		The global transform of the object. If the Object3D has no parent, then it's identical to
+		the local transform [page:.matrix].
+		</p>
+
+		<h3>[property:Boolean matrixWorldNeedsUpdate]</h3>
+		<p>
+		When this is set, it calculates the matrixWorld in that frame and resets this property
+		 to false. Default is *false*.
+		</p>
+
+		<h3>[property:Matrix4 modelViewMatrix]</h3>
+		<p>This is passed to the shader and used to calculate the position of the object.</p>
+
+		<h3>[property:String name]</h3>
+		<p>Optional name of the object (doesn't need to be unique). Default is an empty string.</p>
+
+		<h3>[property:Matrix3 normalMatrix]</h3>
+		<p>
+		This is passed to the shader and used to calculate lighting for the object. It is the transpose of the inverse of the upper left 3x3 sub-matrix of this object's modelViewMatrix.<br /><br />
+
+		The reason for this special matrix is that simply using the modelViewMatrix could result in a non-unit length of normals (on scaling) or in a non-perpendicular direction (on non-uniform scaling).<br /><br />
+
+		On the other hand the translation part of the modelViewMatrix is not relevant for the calculation of normals. Thus a Matrix3 is sufficient.
+		</p>
+
+		<h3>[property:function onAfterRender]</h3>
+		<p>
+		An optional callback that is executed immediately after the Object3D is rendered.
+		This function is called with the following parameters: renderer, scene, camera, geometry,
+		material, group.
+		</p>
+
+		<h3>[property:function onBeforeRender]</h3>
+		<p>
+		An optional callback that is executed immediately before the Object3D is rendered.
+		This function is called with the following parameters: renderer, scene, camera, geometry,
+		material, group.
+		</p>
+
+		<h3>[property:Object3D parent]</h3>
+		<p>Object's parent in the [link:https://en.wikipedia.org/wiki/Scene_graph scene graph]. An object can have at most
+		one parent.</p>
+
+		<h3>[property:Vector3 position]</h3>
+		<p>A [page:Vector3] representing the object's local position. Default is (0, 0, 0).</p>
+
+		<h3>[property:Quaternion quaternion]</h3>
+		<p>Object's local rotation as a [page:Quaternion Quaternion].</p>
+
+		<h3>[property:Boolean receiveShadow]</h3>
+		<p>Whether the material receives shadows. Default is *false*.</p>
+
+		<h3>[property:Number renderOrder]</h3>
+		<p>
+		This value allows the default rendering order of [link:https://en.wikipedia.org/wiki/Scene_graph scene graph]
+		objects to be overridden although opaque and transparent objects remain sorted independently.
+		Sorting is from lowest to highest renderOrder. Default value is *0*.
+		</p>
+
+		<h3>[property:Euler rotation]</h3>
+		<p>
+		Object's local rotation (see [link:https://en.wikipedia.org/wiki/Euler_angles Euler angles]), in radians.
+		</p>
+
+		<h3>[property:Vector3 scale]</h3>
+		<p>
+		The object's local scale. Default is [page:Vector3]( 1, 1, 1 ).
+		</p>
+
+		<h3>[property:Vector3 up]</h3>
+		<p>
+		This is used by the [page:.lookAt lookAt] method, for example, to determine the orientation of the result.<br />
+		Default is [page:Object3D.DefaultUp] - that is, ( 0, 1, 0 ).
+		</p>
+
+		<h3>[property:object userData]</h3>
+		<p>
+		An object that can be used to store custom data about the Object3D. It should not hold
+		references to functions as these will not be cloned.
+		</p>
+
+		<h3>[property:String uuid]</h3>
+		<p>
+		[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance.
+		This gets automatically assigned, so this shouldn't be edited.
+		</p>
+
+		<h3>[property:Boolean visible]</h3>
+		<p>Object gets rendered if *true*. Default is *true*.</p>
+
+
+
+
+		<h2>Static Properties</h2>
+		<p>
+			Static properties and methods are defined per class rather than per instance of that class.
+			This means that changing [page:Object3D.DefaultUp] or [page:Object3D.DefaultMatrixAutoUpdate]
+			will change the values of [page:.up up] and [page:.matrixAutoUpdate matrixAutoUpdate] for
+			<em>every</em>	instance of Object3D (or derived classes)	created after the change has

+			Set to ( 0, 1, 0 ) by default.
+		</p>
+
+		<h3>[property:Vector3 DefaultMatrixAutoUpdate]</h3>
+		<p>
+			The default setting for [page:.matrixAutoUpdate matrixAutoUpdate] for newly created Object3Ds.<br />

+		<h2>Constructor</h2>
+
+		<h3>[name]( [param:Vector3 origin], [param:Vector3 direction], [param:Float near], [param:Float far] ) {</h3>
+		<p>
+		[page:Vector3 origin] — The origin vector where the ray casts from.<br />
+		[page:Vector3 direction] — The direction vector that gives direction to the ray. Should be normalized.<br />
+		[page:Float near] — All results returned are further away than near. Near can't be negative. Default value is 0.<br />
+		[page:Float far] — All results returned are closer than far. Far can't be lower than near. Default value is Infinity.
+		</p>
+		<p>
+		This creates a new raycaster object.<br />
+		</p>
+
+
+		<h2>Properties</h2>
+
+		<h3>[property:float far]</h3>
+		<p>
+		The far factor of the raycaster. This value indicates which objects can be discarded based on the distance.
+		This value shouldn't be negative and should be larger than the near property.
+		</p>
+
+		<h3>[property:float linePrecision]</h3>
+		<p>
+		The precision factor of the raycaster when intersecting [page:Line] objects.
+		</p>
+
+		<h3>[property:float near]</h3>
+		<p>
+		The near factor of the raycaster. This value indicates which objects can be discarded based on the distance.
+		This value shouldn't be negative and should be smaller than the far property.
+		</p>
+
+		<h3>[property:Object params]</h3>
+		<p>
+		An object with the following properties:
+
+			<code>
+{
+	Mesh: {},
+	Line: {},
+	LOD: {},
+	Points: { threshold: 1 },
+	Sprite: {}
+}
+			</code>
+
+		</p>
+
+		<h3>[property:Ray ray]</h3>
+		<p>The [Page:Ray] used for the raycasting.</p>
+
+
+		<h2>Methods</h2>
+
+		<h3>[method:null set]( [param:Vector3 origin], [param:Vector3 direction] )</h3>
+		<p>
+		[page:Vector3 origin] — The origin vector where the ray casts from.<br />
+		[page:Vector3 direction] — The normalized direction vector that gives direction to the ray.
+		</p>
+		<p>
+		Updates the ray with a new origin and direction.
+		</p>
+
+		<h3>[method:null setFromCamera]( [param:Vector2 coords], [param:Camera camera] )</h3>
+		<p>
+		[page:Vector2 coords] — 2D coordinates of the mouse, in normalized device coordinates (NDC)---X and Y components should be between -1 and 1.<br />
+		[page:Camera camera] — camera from which the ray should originate
+		</p>
+		<p>
+		Updates the ray with a new origin and direction.
+		</p>
+
+		<h3>[method:Array intersectObject]( [param:Object3D object], [param:Boolean recursive], [param:Array optionalTarget] )</h3>
+		<p>
+		[page:Object3D object] — The object to check for intersection with the ray.<br />
+		[page:Boolean recursive] — If true, it also checks all descendants. Otherwise it only checks intersecton with the object. Default is false.<br />
+		[page:Array optionalTarget] — (optional) target to set the result. Otherwise a new [page:Array] is instantiated. If set, you must clear this array prior to each call (i.e., array.length = 0;).
+		</p>
+		<p>
+		Checks all intersection between the ray and the object with or without the descendants. Intersections are returned sorted by distance, closest first. An array of intersections is returned...
+		</p>
+		<code>
+				[ { distance, point, face, faceIndex, object }, ... ]
+		</code>
+		<p>
+			[page:Float distance] – distance between the origin of the ray and the intersection<br />
+			[page:Vector3 point] – point of intersection, in world coordinates<br />
+			[page:Face3 face] – intersected face<br />
+			[page:Integer faceIndex] – index of the intersected face<br />
+			[page:Object3D object] – the intersected object<br />
+			[page:Vector2 uv] - U,V coordinates at point of intersection
+		</p>
+		<p>
+		*Raycaster* delegates to the [page:Object3D.raycast raycast] method of the passed object, when evaluating whether the ray intersects the object or not. This allows [page:Mesh meshes] to respond differently to ray casting than [page:Line lines] and [page:Points pointclouds].
+		</p>
+		<p>
+		*Note* that for meshes, faces must be pointed towards the origin of the [page:.ray ray] in order to be detected; intersections of the ray passing through the back of a face will not be detected. To raycast against both faces of an object, you'll want to set the [page:Mesh.material material]'s [page:Material.side side] property to *THREE.DoubleSide*.
+		</p>
+
+		<h3>[method:Array intersectObjects]( [param:Array objects], [param:Boolean recursive], [param:Array optionalTarget] )</h3>
+		<p>
+		[page:Array objects] — The objects to check for intersection with the ray.<br />
+		[page:Boolean recursive] — If true, it also checks all descendants of the objects. Otherwise it only checks intersecton with the objects. Default is false.<br />
+		[page:Array optionalTarget] — (optional) target to set the result. Otherwise a new [page:Array] is instantiated. If set, you must clear this array prior to each call (i.e., array.length = 0;).
+		</p>
+		<p>
+		Checks all intersection between the ray and the objects with or without the descendants. Intersections are returned sorted by distance, closest first. Intersections are of the same form as those returned by [page:.intersectObject].

+		type must either be specified as an array of the corresponding THREE objects or as a flat
+		array containing the data of all the objects. In other words; GLSL primitives in arrays
+		must not be represented by arrays. This rule does not apply transitively.

+
+		<p class="desc">
+		An abstract base class for creating a [name] object that contains methods for interpolation.
+		For an array of [name]s see [page:CurvePath].
+		</p>
+
+		<h2>Constructor</h2>
+
+
+		<h3>[name]()</h3>
+		<p>
+		This constructor creates a new [name].
+		</p>
+
+		<h2>Properties</h2>
+
+		<h3>[property:Integer arcLengthDivisions]</h3>
+		<p>This value determines the amount of divisions when calculating the cumulative segment lengths of a curve via [page:.getLengths].
+			To ensure precision when using methods like [page:.getSpacedPoints], it is recommended to increase [page:.arcLengthDivisions] if the curve is very large. Default is 200.</p>
+
+		<h2>Methods</h2>
+
+		<h3>[method:Vector getPoint]( [param:Float t], [param:Vector optionalTarget] )</h3>
+		<p>
+			[page:Float t] - A position on the curve. Must be in the range [ 0, 1 ]. <br>
+			[page:Vector optionalTarget] — (optional) If specified, the result will be copied into this Vector,
+			otherwise a new Vector will be created. <br /><br />
+
+			Returns a vector for a given position on the curve.
+		</p>
+
+		<h3>[method:Vector getPointAt]( [param:Float u], [param:Vector optionalTarget] )</h3>
+		<p>
+			[page:Float u] - A position on the curve according to the arc length. Must be in the range [ 0, 1 ]. <br>
+			[page:Vector optionalTarget] — (optional) If specified, the result will be copied into this Vector,
+			otherwise a new Vector will be created. <br /><br />
+
+			Returns a vector for a given position on the curve according to the arc length.
+		</p>
+
+		<h3>[method:Array getPoints]( [param:Integer divisions] )</h3>
+		<p>
+			divisions -- number of pieces to divide the curve into. Default is *5*.<br /><br />
+
+			Returns a set of divisions + 1 points using getPoint( t ).
+		</p>
+
+		<h3>[method:Array getSpacedPoints]( [param:Integer divisions] )</h3>
+		<p>
+			divisions -- number of pieces to divide the curve into. Default is *5*.<br /><br />
+
+			Returns a set of divisions + 1 equi-spaced points using getPointAt( u ).
+		</p>
+
+		<h3>[method:Float getLength]()</h3>
+		<p>Get total curve arc length.</p>
+
+		<h3>[method:Array getLengths]( [param:Integer divisions] )</h3>
+		<p>Get list of cumulative segment lengths.</p>
+
+		<h3>[method:null updateArcLengths]()</h3>
+		<p>Update the cumlative segment distance cache.</p>
+
+		<h3>[method:Float getUtoTmapping]( [param:Float u], [param:Float distance] )</h3>
+		<p>
+			Given u in the range ( 0 .. 1 ), returns [page:Float t] also in the range ( 0 .. 1 ).
+			u and t can then be used to give you points which are equidistant from the ends of the curve,
+			using [page:.getPoint].
+		 </p>
+
+		<h3>[method:Vector getTangent]( [param:Float t] )</h3>
+		<p>
+			Returns a unit vector tangent at t. If the derived curve does not implement its
+			tangent derivation, two points a small delta apart will be used to find its gradient
+			which seems to give a reasonable approximation.
+		</p>
+
+		<h3>[method:Vector getTangentAt]( [param:Float u] )</h3>
+		<p>
+			Returns tangent at a point which is equidistant to the ends of the curve from the
+			point given in [page:.getTangent].
+		</p>
+
+		<h3>[method:Object computeFrenetFrames]( [param:Integer segments], [param:Boolean closed] )</h3>
+		<p>
+		Generates the Frenet Frames. Used in geometries like [page:TubeGeometry] or [page:ExtrudeGeometry].
+		</p>
+
+		<h3>[method:Curve clone]()</h3>
+		<p>Creates a clone of this instance.</p>
+
+		<h3>[method:Curve copy]( [param:Curve source] )</h3>
+		<p>Copies another [name] object to this instance.</p>
+
+		<h3>[method:Object toJSON]()</h3>
+		<p>Returns a JSON object representation of this instance.</p>
+
+		<h3>[method:Curve fromJSON]( [param:Object json] )</h3>
+		<p>Copies the data from the given JSON object to this instance.</p>

+
+		<h3>[method:null quadraticCurveTo]( [param:Float cpX], [param:Float cpY], [param:Float x], [param:Float y] )</h3>
+		<p>This creates a quadratic curve from the [page:ShapePath.currentPath currentPath]'s

+		<h2>Constructor</h2>
+
+
+		<h3>[name]([param:Array shapes], [param:Object options])</h3>
+		<p>
+		shapes — Shape or an array of shapes. <br />
+		options — Object that can contain the following parameters.
+
+			<ul>
+				<li>curveSegments — int. Number of points on the curves. Default is 12.</li>
+				<li>steps — int. Number of points used for subdividing segments along the depth of the extruded spline. Default is 1.</li>
+				<li>depth — float. Depth to extrude the shape. Default is 100.</li>
+				<li>bevelEnabled — bool. Apply beveling to the shape. Default is true.</li>
+				<li>bevelThickness — float. How deep into the original shape the bevel goes. Default is 6.</li>
+				<li>bevelSize — float. Distance from the shape outline that the bevel extends. Default is bevelThickness - 2.</li>
+				<li>bevelSegments — int. Number of bevel layers. Default is 3.</li>
+				<li>extrudePath — THREE.CurvePath. A 3D spline path along which the shape should be extruded.</li>
+				<li>UVGenerator —  Object. object that provides UV generator functions</li>
+			</ul>
+
+		</p>
+		<p>
+			This object extrudes a 2D shape to a 3D geometry.
+		</p>
+
+		<p>
+			When creating a Mesh with this geometry, if you'd like to have a separate material used for its face
+			and its extruded sides, you can use an array of materials. The first material will be
+			applied to the face; the second material will be applied to the sides.
+		</p>
+
+		<h2>Properties</h2>
+
+		<h3>[property:Object parameters]</h3>
+		<p>
+		An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.

+		The geometry is created by sweeping and calculating vertexes around the Y axis (horizontal sweep) and the Z axis (vertical sweep). Thus, incomplete spheres (akin to <em>'sphere slices'</em>) can be created through the use of different values of phiStart, phiLength, thetaStart and thetaLength, in order to define the points in which we start (or end) calculating those vertices.

+			A light that gets emitted in a specific direction. This light will behave as though it is
+			infinitely far away and the rays produced from it are all parallel. The common use case
+			for this is to simulate daylight; the sun is far enough away that its position can be
+			considered to be infinite, and all light rays coming from it are parallel.<br /><br />
+
+			This light can cast shadows - see the [page:DirectionalLightShadow] page for details.
+		</p>
+
+		<h2>A Note about Position, Target and rotation</h2>
+		<p>
+			A common point of confusion for directional lights is that setting the rotation has no effect.
+			This is because three.js's DirectionalLight is the equivalent to what is often called a 'Target
+			Direct Light' in other applications.<br /><br />
+
+			This means that its direction is calculated as pointing
+			from the light's [page:Object3D.position position] to	the [page:.target target]'s position
+			(as opposed to a 'Free Direct Light' that just has a rotation component).<br /><br />
+
+			The reason for this is to allow the light to cast shadows - the [page:.shadow shadow]
+			camera needs a position to calculate shadows from.<br /><br />
+
+			See the [page:.target target] property below for details on updating the target.
+		</p>

+
+		<h2>Constructor</h2>
+
+		<h3>[name]( [param:Integer color], [param:Float intensity] )</h3>
+		<p>
+			[page:Integer color] - (optional) hexadecimal color of the light. Default is 0xffffff (white).<br />

+
+			Creates a new [name].
+		</p>
+
+		<h2>Properties</h2>
+
+		See the base [page:Light Light] class for common properties.
+
+		<h3>[property:Boolean castShadow]</h3>
+		<p>
+			If set to *true* light will cast dynamic shadows. *Warning*: This is expensive and
+			requires tweaking to get shadows looking right. See the [page:DirectionalLightShadow] for details.
+			The default is *false*.

+			Used to check whether this or derived classes are directional lights. Default is *true*.<br /><br />
+

+
+
+		<h3>[property:Vector3 position]</h3>
+		<p>
+			This is set equal to [page:Object3D.DefaultUp] (0, 1, 0), so that the light shines from the top down.

+
+		<h3>[property:DirectionalLightShadow shadow]</h3>
+		<p>
+			A [page:DirectionalLightShadow] used to calculate shadows for this light.
+		</p>
+
+		<h3>[property:Object3D target]</h3>
+		<p>
+			The DirectionalLight points from its [page:.position position] to target.position. The default
+			position of the target is *(0, 0, 0)*.<br />
+
+			*Note*: For the target's position to be changed to anything other than the default,
+			it must be added to the [page:Scene scene] using
+		</p>
+		<code>
+		scene.add( light.target );
+		</code>
+		<p>
+			This is so that the target's [page:Object3D.matrixWorld matrixWorld] gets automatically
+			updated each frame.<br /><br />
+
+			It is also possible to set the target to be another object in the scene (anything with a
+			[page:Object3D.position position] property), like so:
+		</p>
+		<code>
+		var targetObject = new THREE.Object3D();
+		scene.add(targetObject);
+
+		light.target = targetObject;
+		</code>
+		<p>

+			Default is *1*.
+		</p>
+

+		</p>
+
+		<h2>Properties</h2>
+
+		See the base [page:Light Light] class for common properties.
+
+		<h3>[property:Float angle]</h3>
+		<p>
+			Maximum extent of the spotlight, in radians, from its direction. Should be no more than
+			*Math.PI/2*. The default is *Math.PI/3*.
+		</p>
+
+
+		<h3>[property:Boolean castShadow]</h3>
+		<p>
+			If set to *true* light will cast dynamic shadows. *Warning*: This is expensive and
+			requires tweaking to get shadows looking right. See the [page:SpotLightShadow] for details.
+			The default is *false*.
+		</p>
+
+		<h3>[property:Float decay]</h3>
+		<p>
+			The amount the light dims along the distance of the light.<br />
+			In [page:WebGLRenderer.physicallyCorrectLights physically correct] mode, decay = 2 leads to
+			physically realistic light falloff. The default is *1*.
+		</p>
+
+		<h3>[property:Float distance]</h3>
+		<p>
+			If non-zero, light will attenuate linearly from maximum intensity at the light's
+			position down to zero at this distance from the light. Default is *0.0*.
+		</p>
+
+		<h3>[property:Boolean isSpotLight]</h3>
+		<p>
+			Used to check whether this or derived classes are spot lights. Default is *true*.<br /><br />
+
+			You should not change this, as it used internally for optimisation.
+		</p>
+
+		<h3>[property:Float penumbra]</h3>
+		<p>
+			Percent of the spotlight cone that is attenuated due to penumbra. Takes values between
+			zero and 1. The default is *0.0*.
+		</p>
+
+		<h3>[property:Vector3 position]</h3>
+		<p>
+			This is set equal to [page:Object3D.DefaultUp] (0, 1, 0), so that the light shines from the top down.
+		</p>
+
+		<h3>[property:Float power]</h3>
+		<p>
+			The light's power.<br />
+			In [page:WebGLRenderer.physicallyCorrectLights physically correct] mode, the luminous
+			power of the light measured in lumens. Default is *4Math.PI*. <br /><br />
+
+			This is directly related to the [page:.intensity intensity] in the ratio
+			<code>
+				power = intensity * &pi;
+			</code>
+			and changing this will also change the intensity.
+		</p>
+
+		<h3>[property:SpotLightShadow shadow]</h3>
+		<p>
+			A [page:SpotLightShadow] used to calculate shadows for this light.
+		</p>
+
+
+		<h3>[property:Object3D target]</h3>
+		<p>
+			The Spotlight points from its [page:.position position] to target.position. The default
+			position of the target is *(0, 0, 0)*.<br />
+
+			*Note*: For the target's position to be changed to anything other than the default,
+			it must be added to the [page:Scene scene] using
+			<code>
+				scene.add( light.target );
+			</code>
+
+			This is so that the target's [page:Object3D.matrixWorld matrixWorld] gets automatically
+			updated each frame.<br /><br />
+
+			It is also possible to set the target to be another object in the scene (anything with a
+			[page:Object3D.position position] property), like so:
+			<code>
+var targetObject = new THREE.Object3D();
+scene.add(targetObject);
+
+light.target = targetObject;
+			</code>
+			The spotlight will now track the target object.

+
+		<p class="desc">
+			A low level class for loading resources with XMLHttpRequest, used internaly by most loaders.
+			It can also be used directly to load any file type that does not have a loader.
+		</p>
+
+		<h2>Example</h2>
+		<p>
+			[example:webgl_loader_msgpack WebGL / loader / msgpack]<br />
+			[example:webgl_morphtargets_human WebGL / morphtargets / human]<br />
+		</p>
+		<code>
+		var loader = new THREE.FileLoader();
+
+		//load a text file and output the result to the console
+		loader.load(
+			// resource URL
+			'example.txt',
+
+			// onLoad callback
+			function ( data ) {
+				// output the text to the console
+				console.log( data )
+			},
+
+			// onProgress callback
+			function ( xhr ) {
+				console.log( (xhr.loaded / xhr.total * 100) + '% loaded' );
+			},
+
+			// onError callback
+			function ( err ) {
+				console.error( 'An error happened' );
+			}
+		);
+		</code>
+
+		<p>
+			<em>Note:</em> The cache must be enabled using
+			<code>THREE.Cache.enabled = true;</code>
+			This is a global property and only needs to be set once to be used by all loaders that use FileLoader internally.
+			[page:Cache Cache] is a cache module that holds the response from each request made through this loader, so each file is requested once.
+		</p>
+
+
+		<h2>Constructor</h2>
+
+		<h3>[name] ( [param:LoadingManager manager] )</h3>
+		<p>
+			[page:LoadingManager manager] — The [page:LoadingManager loadingManager] for the loader to use.

+		<h3>[method:null load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
+		<p>
+			[page:String url] — the path or URL to the file. This can also be a
+				[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
+			[page:Function onLoad] (optional) — Will be called when loading completes. The argument will be the loaded response.<br />
+			[page:Function onProgress] (optional) — Will be called while load progresses. The argument will be the XMLHttpRequest instance,
+				which contains .[page:Integer total] and .[page:Integer loaded] bytes.<br />

+		<p>
+			Set the expected [link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types mimeType]
+			of the file being loaded. Note that in many cases this will be determined automatically, so by default it is *undefined*.
+		</p>
+
+		<h3>[method:FileLoader setPath]( [param:String path] )</h3>
+		<p>
+			Set the base path or URL from which to load files. This can be useful if
+			you are loading many models from the same directory.
+		</p>

+		<h3>[method:FileLoader setResponseType]( [param:String responseType] )</h3>
+		<p>
+			Change the response type. Valid values are:<br />
+			[page:String text] or empty string (default) - returns the data as [page:String string].<br />
+			[page:String arraybuffer] - loads the data into a [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer ArrayBuffer] and returns that.<br />
+			[page:String blob] - returns the data as a [link:https://developer.mozilla.org/en/docs/Web/API/Blob Blob].<br />
+			[page:String document] - parses the file using the [link:https://developer.mozilla.org/en-US/docs/Web/API/DOMParser DOMParser].<br />
+			[page:String json] - parses the file using [link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse JSON.parse].<br />
+		</p>
+
+		<h3>[method:FileLoader setWithCredentials]( [param:Boolean value] )</h3>
+		<p>
+			Whether the XMLHttpRequest uses credentials such as cookies, authorization headers or
+			TLS client certificates. See [link:https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials XMLHttpRequest.withCredentials].<br />
+			Note that this has no effect if you are loading files locally or from the same domain.

+			coming from drag-and-drop events, WebSockets, WebRTC, or other APIs. An
+			example showing how to load an in-memory model using Blob URLs is below.
+		</p>
+
+		<code>
+		// Blob or File objects created when dragging files into the webpage.
+		var blobs = {'fish.gltf': blob1, 'diffuse.png': blob2, 'normal.png': blob3};
+
+		var manager = new THREE.LoadingManager();
+
+		// Initialize loading manager with URL callback.
+		var objectURLs = [];
+		manager.setURLModifier( ( url ) => {
+
+			url = URL.createObjectURL( blobs[ url ] );
+
+			objectURLs.push( url );
+
+			return url;
+
+		} );
+
+		// Load as usual, then revoke the blob URLs.
+		var loader = new THREE.GLTFLoader( manager );
+		loader.load( 'fish.gltf', (gltf) => {
+
+			scene.add( gltf.scene );
+
+			objectURLs.forEach( ( url ) => URL.revokeObjectURL( url ) );
+
+		});
+		</code>
+
+		<h2>Constructor</h2>
+
+		<h3>[name]( [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
+		<p>
+		[page:Function onLoad] — (optional) this function will be called when all loaders are done.<br />
+		[page:Function onProgress] — (optional) this function will be called when an item is complete.<br />
+		[page:Function onError] — (optional) this function will be called a loader encounters errors. <br />
+
+		Creates a new [name].
+		</p>
+
+
+		<h2>Properties</h2>
+
+		<h3>[property:Function onStart]</h3>
+		<p>
+			This function will be called when loading starts.
+			The arguments are:<br />
+			[page:String url] — The url of the item just loaded.<br />
+			[page:Integer itemsLoaded] — the number  of items already loaded so far.<br />
+			[page:Iteger itemsTotal] — the total amount of items to be loaded.<br /><br />
+
+			By default this is undefined.
+		</p>
+
+		<h3>[property:Function onLoad]</h3>
+		<p>
+			This function will be called when all loading is completed. By default this is undefined,
+			unless passed in the constructor.
+		</p>
+
+		<h3>[property:Function onProgress]</h3>
+		<p>
+		This function will be called when an item is complete.
+		The arguments are:<br />
+		[page:String url] — The url of the item just loaded.<br />
+		[page:Integer itemsLoaded] — the number  of items already loaded so far.<br />
+		[page:Iteger itemsTotal] — the total amount of items to be loaded.<br /><br />
+
+		By default this is undefined, unless passed in the constructor.
+		</p>
+
+		<h3>[property:Function onError]</h3>
+		<p>
+			This function will be called when any item errors, with the argument:<br />
+			[page:String url] — The url of the item that errored.<br /><br />

+			By default this is undefined, unless passed in the constructor.
+		</p>
+
+
+		<h2>Methods</h2>
+
+		<h3>[method:null setURLModifier]( [param:Function callback] )</h3>
+		<p>
+		[page:Function callback] — URL modifier callback. Called with [page:String url] argument, and
+		must return [page:String resolvedURL].<br /><br />
+
+		If provided, the callback will be passed each resource URL before a request is sent. The
+		callback may return the original URL, or a new URL to override loading behavior. This
+		behavior can be used to load assets from .ZIP files, drag-and-drop APIs, and Data URIs.
+		</p>
+
+		<h3>[method:String resolveURL]( [param:String url] )</h3>
+		<p>
+		[page:String url] — the url to load<br /><br />
+
+		Given a URL, uses the URL modifier callback (if any) and returns a resolved URL. If no
+		URL modifier is set, returns the original URL.
+		</p>
+
+		<br /><br />
+		<p>
+			<em>Note: The following methods are designed to be called internally by loaders. You shouldn't call
+			them directly.</em>
+		</p>
+
+		<h3>[method:null itemStart]( [param:String url] )</h3>
+		<p>
+		[page:String url] — the url to load<br /><br />

+		</p>
+
+
+		<h3>[method:null itemError]( [param:String url] )</h3>
+		<p>
+		[page:String url] — the loaded url<br /><br />
+
+		This should be called by any loader using the manager when the loader errors loading an url.
+		</p>

+    默认值为*1.0*。 <br/>
+
+</p>
+

+
+		<p class="desc"> 一种基于物理的标准材质，使用Metallic-Roughness工作流程。<br /><br />
+			基于物理的渲染（PBR）最近已成为许多3D应用程序的标准，例如[link:https://blogs.unity3d.com/2014/10/29/physically-based-shading-in-unity-5-a-primer/ Unity]，
+			[link:https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/PhysicallyBased/ Unreal]和
+			[link:http://area.autodesk.com/blogs/the-3ds-max-blog/what039s-new-for-rendering-in-3ds-max-2017 3D Studio Max]。<br /><br />
+			这种方法与旧方法的不同之处在于，不使用近似值来表示光与表面的相互作用，而是使用物理上正确的模型。
+			我们的想法是，不是在特定照明下调整材质以使其看起来很好，而是可以创建一种材质，能够“正确”地应对所有光照场景。<br /><br />
+
+			在实践中，该材质提供了比[page:MeshLambertMaterial] 或[page:MeshPhongMaterial] 更精确和逼真的结果，代价是计算成本更高。<br /><br />
+
+
+			计算着色的方式与[page:MeshPhongMaterial]相同，都使用[link:https://en.wikipedia.org/wiki/Phong_shading Phong]着色模型，
+			这会计算每个像素的阴影（即在[link:https://en.wikipedia.org/wiki/Shader#Pixel_shaders fragment shader]，
+			AKA pixel shader中）， 与[page:MeshLambertMaterial]使用的Gouraud模型相比，该模型的结果更准确，但代价是牺牲一些性能。<br /><br />
+
+			请注意，为获得最佳效果，您在使用此材质时应始终指定[page:.envMap environment map]。<br /><br />
+			有关PBR概念的非技术性介绍以及如何设置PBR材质，请查看[link:https://www.marmoset.co marmoset]成员的这些文章：

+
+		<p class="desc"> 使用自定义shader渲染的材质。
+			shader是一个用[link:https://www.khronos.org/files/opengles_shading_language.pdf GLSL]编写的小程序 ，在GPU上运行。
+			您可能需要使用自定义shader，如果你要：
+		<ul>
+			<li>要实现内置 [page:Material materials] 之外的效果。</li>
+			<li>将许多对象组合成单个[page:Geometry]或[page:BufferGeometry]以提高性能。</li>
+		</ul>
+		使用*ShaderMaterial*时需要注意以下注意事项：
+		<ul>
+			<li>*ShaderMaterial* 只有使用 [page:WebGLRenderer] 才可以绘制正常，
+				因为 [link:https://en.wikipedia.org/wiki/Shader#Vertex_shaders vertexShader]
+				和 [link:https://en.wikipedia.org/wiki/Shader#Pixel_shaders fragmentShader]
+				属性中GLSL代码必须使用WebGL来编译并运行在GPU中。
+			</li>
+			<li> 从 THREE r72开始，不再支持在ShaderMaterial中直接分配属性。
+				必须使用 [page:BufferGeometry]实例 (而不是 [page:Geometry] 实例)，使用[page:BufferAttribute]实例来定义自定义属性。
+			</li>
+			<li> 从 THREE r77开始，[page:WebGLRenderTarget] 或 [page:WebGLRenderTargetCube] 实例不再被用作uniforms。
+				必须使用它们的[page:Texture texture] 属性。
+			</li>
+			<li> 内置attributes和uniforms与代码一起传递到shaders。
+				如果您不希望[page:WebGLProgram]向shader代码添加任何内容，则可以使用[page:RawShaderMaterial]而不是此类。
+			</li>
+			<li> 您可以使用指令#pragma unroll_loop，以便通过shader预处理器在GLSL中展开for循环。
+				该指令必须放在循环的正上方。循环格式必须与定义的标准相对应。
+				<ul>
+					<li> 循环必须标准化[link:https://en.wikipedia.org/wiki/Normalized_loop normalized]。
+					</li>
+					<li>
+						循环变量必须是*i*。
+					</li>
+					<li>
+						循环必须使用某种空格格式。
+					</li>
+				</ul>

+
+		<h2>顶点着色器和片元着色器(Vertex shaders and fragment shaders)</h2>
+
+		<div>
+			<p>您可以为每种材质指定两种不同类型的shaders：:</p>
+			<ul>
+				<li> 顶点着色器首先运行; 它接收*attributes*，
+					计算/操纵每个单独顶点的位置，并将其他数据（*varying*s）传递给片元着色器。
+				</li>
+				<li>
+					片元（或像素）着色器后运行; 它设置渲染到屏幕的每个单独的“片元”（像素）的颜色。
+				</li>
+			</ul>
+			<p>shader中有三种类型的变量: uniforms, attributes, 和 varyings:</p>
+			<ul>
+				<li>*Uniforms*是所有顶点都具有相同的值的变量。
+					比如灯光，雾，和阴影贴图就是被储存在uniforms中的数据。
+					uniforms可以通过顶点着色器和片元着色器来访问。
+				</li>
+				<li> *Attributes* 与每个顶点关联的变量。例如，顶点位置，法线和顶点颜色都是存储在attributes中的数据。attributes <em>只</em>
+					可以在顶点着色器中访问。
+				</li>
+				<li> *Varyings* 是从顶点着色器传递到片元着色器的变量。对于每一个片元，每一个varying的值将是相邻顶点值的平滑插值。
+				</li>
+			</ul>
+			<p> 注意：在shader <em>内部</em>，uniforms和attributes就像常量；你只能使用JavaScript代码通过缓冲区来修改它们的值。
+			</p>
+		</div>
+
+
+	<h2>内置attributes 和 uniforms(Built-in attributes and uniforms)</h2>
+
+	<div>
+			<p>
+				[page:WebGLRenderer]默认情况下为shader提供了许多attributes和uniforms；
+				这些变量定义在shader程序编译时被自动添加到*片元着色器*和*顶点着色器*代码的前面，你不需要自己声明它们。
+				这些变量的描述请参见[page:WebGLProgram]。
+			</p>
+			<p>
+				这些uniforms或attributes（例如，那些和照明，雾等相关的）要求属性设置在材质上，
+				以便 [page:WebGLRenderer]来拷贝合适的值到GPU中。
+				如果你想在自己的shader中使用这些功能，请确保设置这些标志。
+			</p>
+			<p>
+				如果你不希望[page:WebGLProgram] 向你的shader代码中添加任何东西，
+				你可以使用[page:RawShaderMaterial] 而不是这个类。
+			</p>
+		</div>
+
+
+		<h2>自定义 attributes 和 uniforms(Custom attributes and uniforms)</h2>
+
+		<div>
+			<p>
+				自定义attributes和uniforms必须在GLSL着色器代码中声明（在 *vertexShader* 和/或 *fragmentShader* 中)。
+				自定义uniforms必须定义为 *ShaderMaterial* 的  *uniforms* 属性，
+				而任何自定义attribtes必须通过[page:BufferAttribute]实例来定义。
+				注意 *varying*s 只需要在shader代码中声明（而不必在材质中）。
+			</p>
+			<p> 要声明一个自定义属性，更多细节请参考[page:BufferGeometry]页面，
+				以及 [page:BufferAttribute] 页面关于*BufferAttribute* 接口。
+			</p>
+			<p>
+				当创建attributes时，您创建的用来保存属性数据的每个类型化数组（typed array）必须是您的数据类型大小的倍数。
+				比如，如果你的属性是一个[page:Vector3 THREE.Vector3]类型，并且在你的缓存几何模型[page:BufferGeometry]中有3000个顶点，
+				那么你的类型化数组的长度必须是3000 * 3，或者9000（一个顶点一个值）。每个数据类型的尺寸如下表所示：
+			</p>
+
+			<table>
+				<caption><a id="attribute-sizes">属性尺寸</a></caption>
+				<thead>
+					<tr>
+						<th>GLSL 类型</th>
+						<th>JavaScript 类型</th>
+						<th>尺寸</th>
+					</tr>
+				</thead>
+				<tbody>
+					<tr>
+						<td>float</td>
+						<td>[page:Number]</td>
+						<td>1</td>
+					</tr>
+					<tr>
+						<td>vec2</td>
+						<td>[page:Vector2 THREE.Vector2]</td>
+						<td>2</td>
+					</tr>
+					<tr>
+						<td>vec3</td>
+						<td>[page:Vector3 THREE.Vector3]</td>
+						<td>3</td>
+					</tr>
+					<tr>
+						<td>vec3</td>
+						<td>[page:Color THREE.Color]</td>
+						<td>3</td>
+					</tr>
+					<tr>
+						<td>vec4</td>
+						<td>[page:Vector4 THREE.Vector4]</td>
+						<td>4</td>
+					</tr>
+				</tbody>
+			</table>
+
+			<p>
+				请注意，属性缓冲区 <em>不会</em> 在其值更改时自动刷新。要更新自定义属性，
+				需要在模型的[page:BufferAttribute]中设置*needsUpdate*为true。
+				（查看[page:BufferGeometry]了解细节）。
+			</p>
+
+			<p>
+				要声明一个自定义的[page:Uniform]，使用*uniforms*属性：
+			<code>
+			uniforms: {
+				time: { value: 1.0 },
+				resolution: { value: new THREE.Vector2() }
+			}
+			</code>
+			</p>
+
+			<p>
+				在[page:Object3D.onBeforeRender]中，建议根据[page:Object3D object]和[page:Camera camera]来更新自定义[page:Uniform]的值。
+				因为 [page:Material] 可以被[page:Mesh meshes]，[page:Scene]的[page:Matrix4 matrixWorld]以及[page:Camera]共享，
+				会在[page:WebGLRenderer.render]中更新，并会对拥有私有[page:Camera cameras]的[page:Scene scene]的渲染造成影响。

+		</p>
+
+		<h3>[property:Object defaultAttributeValues]</h3>
+		<p> 当渲染的几何体不包含这些属性但材质包含这些属性时，这些默认值将传递给shaders。这可以避免在缓冲区数据丢失时出错。

+
+		</p>
+
+
+		<h3>[property:Object defines]</h3>
+		<p> 使用 #define 指令在GLSL代码为顶点着色器和片段着色器定义自定义常量；每个键/值对产生一行定义语句：
+		<code>
+		defines: {
+			FOO: 15,
+			BAR: true
+		}
+		</code>
+		这将在GLSL代码中产生如下定义语句：
+		<code>
+		#define FOO 15

+		</p>
+
+
+		<h3>[property:Boolean fog]</h3>
+		<p> 定义材质颜色是否受全局雾设置的影响; 如果将fog uniforms传递给shader，则为true。默认值为false。
+		</p>
+
+
+		<h3>[property:String fragmentShader]</h3>
+		<p>
+			片元着色器的GLSL代码。这是shader程序的实际代码。在上面的例子中，
+			*vertexShader*  和 *fragmentShader* 代码是从DOM（HTML文档）中获取的；
+			它也可以作为一个字符串直接传递或者通过AJAX加载。
+		</p>
+
+		<h3>[property:String index0AttributeName]</h3>
+		<p> 如果设置，则调用[link:https://developer.mozilla.org/en-US/docs/Web/API/WebGLRenderingContext/bindAttribLocation gl.bindAttribLocation]
+			将通用顶点索引绑定到属性变量。默认值未定义。
+
+		</p>
+
+		<h3>[property:Boolean isShaderMaterial]</h3>

+		</p>
+
+
+
+
+		<h3>[property:Boolean lights]</h3>
+		<p> 材质是否受到光照的影响。默认值为 *false*。如果传递与光照相关的uniform数据到这个材质，则为true。默认是false。
+		</p>
+
+		<h3>[property:Float linewidth]</h3>
+		<p>控制线框宽度。默认值为1。<br /><br />
+			由于[link:https://www.khronos.org/registry/OpenGL/specs/gl/glspec46.core.pdf OpenGL Core Profile]与大多数平台上[page:WebGLRenderer WebGL]渲染器的限制，无论如何设置该值，线宽始终为1。
+		</p>
+
+
+		<h3>[property:Boolean morphTargets]</h3>
+		<p> 定义材质是否使用 morphTargets。如果将morphTarget attributes传递到此shader，则为true。
+		</p>
+
+		<h3>[property:boolean morphNormals]</h3>

+			这里 *value* 是uniform的值。名称必须匹配 uniform 的name，和GLSL代码中的定义一样。
+			注意，uniforms逐帧被刷新，所以更新uniform值将立即更新GLSL代码中的相应值。
+		</p>
+
+
+		<h3>[property:Number vertexColors]</h3>
+		<p> 通过定义*colors*属性的生成方式来定义顶点是如何着色的。
+			可选值为[page:Materials THREE.NoColors], [page:Materials THREE.FaceColors] 和
+			[page:Materials THREE.VertexColors]。 缺省为 THREE.NoColors。

+			A class representing [link:http://en.wikipedia.org/wiki/Euler_angles Euler Angles].<br /><br />
+
+			Euler angles describe a rotational transformation by rotating an object on its various
+			axes in specified amounts per axis, and a specified axis order.
+		</p>
+
+		<h2>Example</h2>
+
+		<code>var a = new THREE.Euler( 0, 1, 1.57, 'XYZ' );
+		var b = new THREE.Vector3( 1, 0, 1 );
+		b.applyEuler(a);
+		</code>
+
+
+		<h2>Constructor</h2>
+
+
+		<h3>[name]( [param:Float x], [param:Float y], [param:Float z], [param:String order] )</h3>
+		<p>
+		[page:Float x] - (optional) the angle of the x axis in radians. Default is *0*.<br />
+		[page:Float y] - (optional) the angle of the y axis in radians. Default is *0*.<br />
+		[page:Float z] - (optional) the angle of the z axis in radians. Default is *0*.<br />
+		[page:String order] - (optional) a string representing the order that the rotations are applied,
+		defaults to 'XYZ' (must be upper case).<br /><br />
+
+		</p>
+
+
+		<h2>Properties</h2>
+
+		<h3>[property:Boolean isEuler]</h3>
+		<p>
+			Used to check whether this or derived classes are Eulers. Default is *true*.<br /><br />
+
+			You should not change this, as it used internally for optimisation.
+		</p>
+
+		<h3>[property:String order]</h3>
+		<p>
+			The order in which to apply rotations. Default is 'XYZ', which means that the object will first be
+			rotated around its X axis, then its Y axis and finally its Z axis. Other possibilities are:
+			'YZX', 'ZXY', 'XZY', 'YXZ' and 'ZYX'. These must be in upper case.<br /><br />
+
+			Three.js uses <em>intrinsic</em> Tait-Bryan angles. This means that rotations are performed with respect
+			to the <em>local</em> coordinate system. That is, for order 'XYZ', the rotation is first around the local-X
+			axis (which is the same as the world-X axis), then around local-Y (which may now be different from the
+			world Y-axis), then local-Z (which may be different from the world Z-axis).<br /><br />
+
+			If the order is changed, [page:.onChangeCallback onChangeCallback] will be called.
+		</p>
+
+		<h3>[property:Float x]</h3>
+		<p>
+			The current value of the x component.<br /><br />
+
+			If this is changed, [page:.onChangeCallback onChangeCallback] will be called.
+		</p>
+
+		<h3>[property:Float y]</h3>
+		<p>
+			The current value of the y component.<br /><br />
+
+			If this is changed, [page:.onChangeCallback onChangeCallback] will be called.
+		</p>
+
+		<h3>[property:Float z]</h3>
+		<p>
+			The current value of the z component.<br /><br />
+
+			If this is changed, [page:.onChangeCallback onChangeCallback] will be called.
+		</p>
+
+		<h2>Methods</h2>
+
+		<h3>[method:Euler copy]( [param:Euler euler] )</h3>
+		<p>Copies value of [page:Euler euler] to this euler.</p>
+
+		<h3>[method:Euler clone]()</h3>
+		<p>Returns a new Euler with the same parameters as this one.</p>
+
+		<h3>[method:Boolean equals]( [param:Euler euler] )</h3>
+		<p>Checks for strict equality of this euler and [page:Euler euler].</p>
+
+		<h3>[method:Euler fromArray]( [param:Array array] )</h3>
+		<p>

+
+		<p class="desc">
+			A class representing a 4x4 [link:https://en.wikipedia.org/wiki/Matrix_(mathematics) matrix].<br /><br />
+
+			The most common use of a 4x4 matrix in 3D computer graphics is as a
+			[link:https://en.wikipedia.org/wiki/Transformation_matrix Transformation Matrix].
+			For an introduction to transformation matrices as used in WebGL, check out
+			[link:http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices this tutorial].<br /><br />
+
+			This allows a [page:Vector3] representing a point in 3D space to undergo transformations
+			such as translation, rotation, shear, scale, reflection, orthogonal or perspective projection
+			and so on, by being multiplied by the matrix. This is known as	<em>applying</em>
+			the matrix to the vector.<br /><br />
+
+			Every [page:Object3D] has three associated Matrix4s:
+			<ul>
+				<li>
+					[page:Object3D.matrix]: This stores the local transform of the object. This is the object's transformation relative to its parent.
+				</li>
+				<li>
+					[page:Object3D.matrixWorld]: The global or world transform of the object. If the object has no parent, then this is identical to the local transform stored in [page:Object3D.matrix matrix].
+				</li>
+				<li>
+					[page:Object3D.modelViewMatrix]: This represents the object's transformation relative to the camera's coordinate system.
+					An object's modelViewMatrix is the object's matrixWorld pre-multiplied by the camera's matrixWorldInverse.
+				</li>
+			</ul>
+
+			[page:Camera Cameras] have two additional Matrix4s:
+			<ul>
+				<li>
+					[page:Camera.matrixWorldInverse]: The view matrix - the inverse of the Camera's [page:Object3D.matrixWorld matrixWorld].
+				</li>
+				<li>
+					[page:Camera.projectionMatrix]: Represents the information how to project the scene to clip space.
+				</li>
+			</ul>
+			Note: [page:Object3D.normalMatrix] is not a Matrix4, but a [page:Matrix3].
+		</p>
+
+		<h2>A Note on Row-Major and Column-Major Ordering</h2>
+		<p>
+			The [page:set]() method takes arguments in [link:https://en.wikipedia.org/wiki/Row-_and_column-major_order#Column-major_order row-major]
+			order, while internally they are stored in the [page:.elements elements] array in column-major order.<br /><br />
+
+			This means that calling
+		<code>
+var m = new Matrix4();
+
+m.set( 11, 12, 13, 14,
+       21, 22, 23, 24,
+       31, 32, 33, 34,
+       41, 42, 43, 44 );
+
+		</code>
+		will result in the [page:.elements elements] array containing:
+		<code>
+m.elements = [ 11, 21, 31, 41,
+               12, 22, 32, 42,
+               13, 23, 33, 43,
+               14, 24, 34, 44 ];
+		</code>
+		and internally all calculations are performed using column-major ordering. However, as the actual ordering
+		makes no difference mathematically and most people are used to thinking about matrices in row-major order,
+		the three.js documentation shows matrices in row-major order. Just bear in mind that if you are reading the source
+		code, you'll have to take the [link:https://en.wikipedia.org/wiki/Transpose transpose] of any matrices outlined here to make sense of the calculations.

+		<h2>Static Methods</h2>
+
+		<p>
+			Static methods (as opposed to instance methods) are designed to be called directly from the class,
+			rather than from a specific instance. So to use the static version of, call it like so:
+			<code>
+THREE.Quaternion.slerp( qStart, qEnd, qTarget, t );
+			</code>
+			By contrast, to call the 'normal' or instanced slerp method, you would do the following:
+			<code>
+//instantiate a quaternion with default values
+var q = new THREE.Quaternion();
+
+//call the instanced slerp method
+q.slerp( qb, t )
+			</code>
+
+		</p>
+
+		<h3>[method:Quaternion slerp]( [param:Quaternion qStart], [param:Quaternion qEnd], [param:Quaternion qTarget], [param:Float t] )</h3>

+			[page:Quaternion qStart] - The starting quaternion (where [page:Float t] is 0)<br />
+			[page:Quaternion qEnd] - The ending quaternion (where [page:Float t] is 1)<br />
+			[page:Quaternion qTarget] - The target quaternion that gets set with the result<br />
+			[page:float t] - interpolation factor in the closed interval [0, 1].<br /><br />
+
+			Unlike the normal method, the static version of slerp sets a target quaternion to the result of the slerp operation.
+			<code>
+			// Code setup
+			var startQuaternion = new THREE.Quaternion().set( 0, 0, 0, 1 ).normalize();
+			var endQuaternion = new THREE.Quaternion().set( 1, 1, 1, 1 ).normalize();
+			var t = 0;
+
+			// Update a mesh's rotation in the loop
+			t = ( t + 0.01 ) % 1; // constant angular momentum
+			THREE.Quaternion.slerp( startQuaternion, endQuaternion, mesh.quaternion, t );
+			</code>
+		</p>
+
+
+		<h3>[method:null slerpFlat]( [param:Array dst], [param:Integer dstOffset], [param:Array src0], [param:Integer srcOffset0], [param:Array src1], [param:Integer srcOffset1], [param:Float t] )</h3>

+			Class representing a 2D [link:https://en.wikipedia.org/wiki/Vector_space vector].
+
+			A 2D vector is an ordered pair of numbers (labeled x and y), which can be used to

+		</p>
+
+		<ul>
+			<li>
+				A point in 2D space (i.e. a position on a plane).
+			</li>
+			<li>
+				A direction and length across a plane. In three.js the length will always be the
+				[link:https://en.wikipedia.org/wiki/Euclidean_distance Euclidean distance]
+				(straight-line distance) from (0, 0) to (x, y) and the direction is also
+				measured from (0, 0) towards (x, y).
+			</li>
+			<li>
+				Any arbitrary ordered pair of numbers.
+			</li>
+		</ul>
+
+		<p>
+			There are other things a 2D vector can be used to represent, such as momentum
+			vectors, complex numbers and so on,	however these are the most common uses in three.js.

+		<h2>Example</h2>
+
+		<code>

+		[page:Float x] - the x value of the vector. Default is *0*.<br />
+		[page:Float y] -  the y value of the vector. Default is *0*.<br /><br />

+
+		<p class="desc">Class representing a 3D [link:https://en.wikipedia.org/wiki/Vector_space vector].
+
+		A 3D vector is an ordered triplet of numbers (labeled x, y, and z), which can be used to
+		represent a number of things, such as:
+		</p>
+
+		<ul>
+			<li>
+				A point in 3D space.
+			</li>
+			<li>
+				A direction and length in 3D space. In three.js the length will always be the
+				[link:https://en.wikipedia.org/wiki/Euclidean_distance Euclidean distance]
+				(straight-line distance) from (0, 0, 0) to (x, y, z) and the direction is also
+				measured from (0, 0, 0) towards (x, y, z).
+			</li>
+			<li>
+				Any arbitrary ordered triplet of numbers.
+			</li>
+		</ul>
+
+		<p>
+		There are other things a 3D vector can be used to represent, such as momentum
+		vectors and so on, however these are the most common uses in three.js.

+
+		<p class="desc">Class representing a 4D [link:https://en.wikipedia.org/wiki/Vector_space vector].
+
+		A 4D vector is an ordered quadruplet of numbers (labeled x, y, z, and w), which can be used to
+		represent a number of things, such as:
+		</p>
+
+		<ul>
+			<li>
+				A point in 4D space.
+			</li>
+			<li>
+				A direction and length in 4D space. In three.js the length will always be the
+				[link:https://en.wikipedia.org/wiki/Euclidean_distance Euclidean distance]
+				(straight-line distance) from (0, 0, 0, 0) to (x, y, z, w) and the direction is also
+				measured from (0, 0, 0, 0) towards (x, y, z, w).
+			</li>
+			<li>
+				Any arbitrary ordered quadruplet of numbers.
+			</li>
+		</ul>
+
+		<p>
+		There are other things a 4D vector can be used to represent, however these are the most common uses in three.js.

+			and one for close up (high detail).

+
+
+		<h2>Constructor</h2>
+
+		<h3>[name]( data, width, height, format, type, mapping, wrapS, wrapT, magFilter, minFilter, anisotropy )</h3>
+		<p>
+			The data argument must be an ArrayBuffer or a typed array view.
+			Further parameters correspond to the properties inherited from [page:Texture], where both magFilter and minFilter default to THREE.NearestFilter. The properties flipY and generateMipmaps are intially set to false.
+		</p>
+		<p>
+			The interpretation of the data depends on type and format:
+			If the type is THREE.UnsignedByteType, a Uint8Array will be useful for addressing the texel data.
+			If the format is THREE.RGBAFormat, data needs four values for one texel; Red, Green, Blue and Alpha (typically the opacity). Similarly, THREE.RGBFormat specifies a format where only three values are used for each texel.<br />
+
+			For the packed types, THREE.UnsignedShort4444Type, THREE.UnsignedShort5551Type or THREE.UnsignedShort565Type, all color components of one texel can be addressed as bitfields within an integer element of a Uint16Array.<br />
+
+			In order to use the types THREE.FloatType and THREE.HalfFloatType, the WebGL implementation must support the respective extensions OES_texture_float and OES_texture_half_float. In order to use THREE.LinearFilter for component-wise, bilinear interpolation of the texels based on these types, the WebGL extensions OES_texture_float_linear or OES_texture_half_float_linear must also be present.
+		</p>
+
+		<h2>Example</h2>
+
+		<code>
+		// create a buffer with color data
+
+		var size = width * height;
+		var data = new Uint8Array( 3 * size );
+
+		var r = Math.floor( color.r * 255 );
+		var g = Math.floor( color.g * 255 );
+		var b = Math.floor( color.b * 255 );
+
+		for ( var i = 0; i < size; i ++ ) {
+
+			var stride = i * 3;
+
+			data[ stride ] = r;
+			data[ stride + 1 ] = g;
+			data[ stride + 2 ] = b;
+
+		}
+
+		// used the buffer to create a [name]

+
+
+		<h2>Constructor</h2>
+
+		<h3>[name]( image, mapping, wrapS, wrapT, magFilter, minFilter, format, type, anisotropy, encoding )</h3>
+
+		<h2>Example</h2>
+
+		<code>
+		// load a texture, set wrap mode to repeat
+		var texture = new THREE.TextureLoader().load( "textures/water.jpg" );
+		texture.wrapS = THREE.RepeatWrapping;
+		texture.wrapT = THREE.RepeatWrapping;
+		texture.repeat.set( 4, 4 );
+		</code>
+
+		<h2>Properties</h2>
+
+		<h3>[property:Integer id]</h3>
+		<p>
+		Readonly - unique number for this texture instance.
+		</p>
+
+		<h3>[property:String uuid]</h3>
+		<p>
+		[link:http://en.wikipedia.org/wiki/Universally_unique_identifier UUID] of this object instance.
+		This gets automatically assigned, so this shouldn't be edited.
+		</p>
+
+		<h3>[property:String name]</h3>
+		<p>
+		Optional name of the object (doesn't need to be unique). Default is an empty string.
+		</p>
+
+		<h3>[property:Image image]</h3>
+		<p>
+		An image object, typically created using the [page:TextureLoader.load] method.
+		This can be any image (e.g., PNG, JPG, GIF, DDS) or video (e.g., MP4, OGG/OGV) type supported by three.js.<br /><br />
+
+		To use video as a texture you need to have a playing HTML5
+		video element as a source for your texture image and continuously update this texture
+		as long as video is playing - the [page:VideoTexture VideoTexture] class handles this automatically.
+		</p>
+
+		<h3>[property:array mipmaps]</h3>
+		<p>
+		Array of user-specified mipmaps (optional).
+		</p>
+
+		<h3>[property:number mapping]</h3>
+		<p>
+		How the image is applied to the object. An object type of [page:Textures THREE.UVMapping] is the default,
+		where the U,V coordinates are used to apply the map.<br />
+
+		See the [page:Textures texture constants] page for other mapping types.
+		</p>
+
+		<h3>[property:number wrapS]</h3>
+		<p>
+		This defines how the texture is wrapped horizontally and corresponds to *U* in UV mapping.<br />
+		The default is [page:Textures THREE.ClampToEdgeWrapping], where the edge is clamped to the outer edge texels.
+		The other two choices are [page:Textures THREE.RepeatWrapping] and [page:Textures THREE.MirroredRepeatWrapping].
+		See the [page:Textures texture constants] page for details.
+		</p>
+
+		<h3>[property:number wrapT]</h3>
+		<p>
+		This defines how the texture is wrapped vertically and corresponds to *V* in UV mapping.<br />
+		The same choices are available as for [property:number wrapS].<br /><br />
+
+		NOTE: tiling of images in textures only functions if image dimensions are powers of two
+		 (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, ...) in terms of pixels.
+		 Individual dimensions need not be equal, but each must be a power of two.
+		 This is a limitation of WebGL, not three.js.
+		</p>
+
+		<h3>[property:number magFilter]</h3>
+		<p>
+		How the texture is sampled when a texel covers more than one pixel. The default is
+		 [page:Textures THREE.LinearFilter], which takes the four closest texels and bilinearly interpolates among them.
+		 The other option is [page:Textures THREE.NearestFilter], which uses the value of the closest texel.<br />
+		 See the [page:Textures texture constants] page for details.
+		</p>
+
+		<h3>[property:number minFilter]</h3>
+		<p>
+		How the texture is sampled when a texel covers less than one pixel. The default is
+		[page:Textures THREE.LinearMipMapLinearFilter], which uses mipmapping and a trilinear filter. <br /><br />
+
+		See the [page:Textures texture constants] page for all possible choices.
+		</p>
+
+		<h3>[property:number anisotropy]</h3>
+		<p>
+		The number of samples taken along the axis through the pixel that has the highest density of texels.
+		By default, this value is 1. A higher value gives a less blurry result than a basic mipmap,
+		at the cost of more texture samples being used. Use [page:WebGLRenderer.getMaxAnisotropy renderer.getMaxAnisotropy]() to
+		find the maximum valid anisotropy value for the GPU; this value is usually a power of 2.
+		</p>
+
+		<h3>[property:number format]</h3>
+		<p>
+		The default is [page:Textures THREE.RGBAFormat], although the [page:TextureLoader TextureLoader] will automatically
+		set this to [page:Textures THREE.RGBFormat] for JPG images. <br /><br />
+
+		See the [page:Textures texture constants] page for details of other formats.
+		</p>
+
+		<h3>[property:number type]</h3>
+		<p>
+		This must correspond to the [page:Texture.format .format]. The default is [page:Textures THREE.UnsignedByteType],
+		which will be used for most texture formats.<br /><br />
+
+		See the [page:Textures texture constants] page for details of other formats.
+		</p>
+
+		<h3>[property:Vector2 offset]</h3>
+		<p>
+		How much a single repetition of the texture is offset from the beginning, in each direction U and V.
+		Typical range is *0.0* to *1.0*.  _Note:_ The offset property is a convenience modifier and only affects
+		the Texture's application to the first set of UVs on a model.  If the Texture is used as a map requiring
+		additional UV sets (e.g. the aoMap or lightMap of most stock materials), those UVs must be manually
+		assigned to achieve the desired offset.
+		</p>
+
+		<h3>[property:Vector2 repeat]</h3>
+		<p>
+		How many times the texture is repeated across the surface, in each direction U and V.  If repeat is set
+		greater than 1 in either direction, the corresponding Wrap parameter should also be set to
+		[page:Textures THREE.RepeatWrapping] or [page:Textures THREE.MirroredRepeatWrapping] to achieve the desired
+		tiling effect.  _Note:_ The repeat property is a convenience modifier and only affects
+		the Texture's application to the first set of UVs on a model.  If the Texture is used as a map requiring
+		additional UV sets (e.g. the aoMap or lightMap of most stock materials), those UVs must be manually
+		assigned to achieve the desired repetiton.
+		</p>
+
+		<h3>[property:number rotation]</h3>
+		<p>
+		How much the texture is rotated around the center point, in radians. Postive values are counter-clockwise. Default is *0*.
+		</p>
+
+		<h3>[property:Vector2 center]</h3>
+		<p>
+		The point around which rotation occurs. A value of (0.5, 0.5) corresponds to the center of the texture. Default is (0, 0), the lower left.
+		</p>
+
+		<h3>[property:boolean matrixAutoUpdate]</h3>
+		<p>
+		Whether to update the texture's uv-transform [page:Texture.matrix .matrix] from the texture properties [page:Texture.offset .offset], [page:Texture.repeat .repeat],
+		[page:Texture.rotation .rotation], and [page:Texture.center .center]. True by default.
+		Set this to false if you are specifying the uv-transform matrix directly.
+		</p>
+
+		<h3>[property:Matrix3 matrix]</h3>
+		<p>
+		The uv-transform matrix for the texture. Updated by the renderer from the texture properties [page:Texture.offset .offset], [page:Texture.repeat .repeat],
+		[page:Texture.rotation .rotation], and [page:Texture.center .center] when the texture's [page:Texture.matrixAutoUpdate .matrixAutoUpdate] property is true.
+		When [page:Texture.matrixAutoUpdate .matrixAutoUpdate] property is false, this matrix may be set manually.
+		Default is the identity matrix.
+		</p>
+
+		<h3>[property:boolean generateMipmaps]</h3>
+		<p>
+		Whether to generate mipmaps (if possible) for a texture. True by default. Set this to false if you are
+		creating mipmaps manually.
+		</p>
+
+		<h3>[property:boolean premultiplyAlpha]</h3>
+		<p>
+		False by default, which is the norm for PNG images. Set to true if the RGB values have
+		been stored premultiplied by alpha.
+		</p>
+
+		<h3>[property:boolean flipY]</h3>
+		<p>
+		True by default. Flips the image's Y axis to match the WebGL texture coordinate space.
+		</p>
+
+		<h3>[property:number unpackAlignment]</h3>
+		<p>
+		4 by default. Specifies the alignment requirements for the start of each pixel row in memory.
+		The allowable values are 1 (byte-alignment), 2 (rows aligned to even-numbered bytes),
+		4 (word-alignment), and 8 (rows start on double-word boundaries).
+		See [link:http://www.khronos.org/opengles/sdk/docs/man/xhtml/glPixelStorei.xml glPixelStorei]
+		for more information.
+		</p>
+
+		<h3>[property:number encoding]</h3>
+		<p>
+		[page:Textures THREE.LinearEncoding] is the default.
+		See the [page:Textures texture constants] page for details of other formats.<br /><br />
+
+		Note that if this value is changed on a texture after the material has been used,
+		it is necessary to trigger a Material.needsUpdate for this value to be realized in the shader.
+		</p>
+
+		<h3>[property:Integer version]</h3>
+		<p>
+		This starts at *0* and counts how many times [property:Boolean needsUpdate] is set to *true*.
+		</p>
+
+		<h3>[property:Function onUpdate]</h3>
+		<p>
+		A callback function, called when the texture is updated (e.g., when needsUpdate has been set to true
+		and then the texture is used).
+		</p>
+
+		<h3>[property:Boolean needsUpdate]</h3>
+		<p>
+		Set this to *true* to trigger an update next time the texture is used. Particularly important for setting the wrap mode.
+		</p>
+
+
+		<h2>Methods</h2>
+
+		<h3>[page:EventDispatcher EventDispatcher] methods are available on this class.</h3>
+
+		<h3>[method:null updateMatrix]()</h3>
+		<p>
+		Update the texture's uv-transform [page:Texture.matrix .matrix] from the texture properties [page:Texture.offset .offset], [page:Texture.repeat .repeat],
+		[page:Texture.rotation .rotation], and [page:Texture.center .center].
+		</p>
+
+		<h3>[method:Texture clone]()</h3>
+		<p>
+		Make copy of the texture. Note this is not a "deep copy", the image is shared.

+		Creates a texture for use with a video texture.<br /><br />
+
+		This is almost the same as the base [page:Texture Texture] class, except that it continuosly sets [page:Texture.needsUpdate needsUpdate] to *true* so that the texture is updated as the video plays. Automatic creation of [page:Texture.mipmaps mipmaps] is also disabled.
+		</p>
+
+    <h2>Example</h2>
+
+		<p>[example:webgl_materials_video materials / video ]</p>
+
+		<code>
+//assuming you have created a HTML video element with id="video"
+var video = document.getElementById( 'video' );
+
+var texture = new THREE.VideoTexture( video );
+texture.minFilter = THREE.LinearFilter;
+texture.magFilter = THREE.LinearFilter;
+texture.format = THREE.RGBFormat;
+    </code>
+
+
+		<h2>Constructor</h2>
+		<h3>[name]( [param:Video video], [param:Constant mapping], [param:Constant wrapS], [param:Constant wrapT], [param:Constant magFilter], [param:Constant minFilter], [param:Constant format], [param:Constant type], [param:Number anisotropy] )</h3>
+		<p>
+		[page:Video video] -- The video element to use as the texture. <br />
+
+		[page:Constant mapping] --  How the image is applied to the object. An object type of [page:Textures THREE.UVMapping].
+		See [page:Textures mapping constants] for other choices.<br />
+
+		[page:Constant wrapS] -- The default is [page:Textures THREE.ClampToEdgeWrapping].
+		See [page:Textures wrap mode constants] for other choices.<br />
+
+		[page:Constant wrapT] -- The default is [page:Textures THREE.ClampToEdgeWrapping].
+		See [page:Textures wrap mode constants] for other choices.<br />
+
+		[page:Constant magFilter] -- How the texture is sampled when a texel covers more than one pixel.
+		The default is [page:Textures THREE.LinearFilter]. See [page:Textures magnification filter constants] for other choices.<br />
+
+		[page:Constant minFilter] -- How the texture is sampled when a texel covers less than one pixel.
+		 The default is [page:Textures THREE.LinearMipMapLinearFilter]. See [page:Textures minification filter constants] for other choices.<br />
+
+    [page:Constant format] -- The format used in the texture.
+     See [page:Textures format constants] for other choices.<br />
+
+    [page:Constant type] -- Default is [page:Textures THREE.UnsignedByteType].
+     See [page:Textures type constants] for other choices.<br />
+
+		[page:Number anisotropy] -- The number of samples taken along the axis through the pixel that has the highest density of texels.
+		By default, this value is 1. A higher value gives a less blurry result than a basic mipmap, at the cost of more texture samples being used.
+		Use [page:WebGLrenderer.getMaxAnisotropy renderer.getMaxAnisotropy]() to find the maximum valid anisotropy value for the GPU; this value is usually a power of 2.<br /><br />

+    </p>
+
+		<h3>[property:boolean needsUpdate]</h3>
+		<p>
+		You will not need to set this manually here as it is handled by the [page:VideoTexture.update update] method.

+
+		<h2>Methods</h2>
+
+    <p>
+    See the base [page:Texture Texture] class for common methods.
+    </p>
+
+    <h3>[method:null update]()</h3>
+		<p>
+		This is called automatically and sets [property:boolean needsUpdate] to *true* every time
+    a new frame is available.

+		<p>Textures containing color information (.map, .emissiveMap, and .specularMap) always use sRGB colorspace in

+		renderer.gammaFactor = 2.2;

+	<h1>[name]</h1>
+	<br />
+
+	<p>
+		This guide provides a brief overview of the basic components of a web-based VR application
+		made with three.js.
+	</p>
+
+	<h2>Workflow</h2>
+
+	<p>
+		First, you have to include [link:https://github.com/mrdoob/three.js/blob/master/examples/js/vr/WebVR.js WebVR.js]
+		into your project.
+	</p>
+
+	<code>
+&lt;script src="/path/to/WebVR.js"&gt;&lt;/script&gt;
+	</code>
+
+	<p>
+		*WEBVR.createButton()* does two important things: It creates a button which indicates
+		VR compatibility. Besides, it initiates a VR session if the user activates the button. The only thing you have
+		to do is to add the following line of code to your app.
+	</p>
+
+	<code>
+document.body.appendChild( WEBVR.createButton( renderer ) );
+	</code>
+
+	<p>
+		Next, you have to tell your instance of *WebGLRenderer* to enable VR rendering.
+	</p>
+
+	<code>
+renderer.vr.enabled = true;
+	</code>
+
+	<p>
+		Finally, you have to adjust your animation loop since we can't use our well known
+		*window.requestAnimationFrame()* function. For VR projects we use [page:WebGLRenderer.setAnimationLoop setAnimationLoop]. 
+		The minimal code looks like this:
+	</p>
+
+	<code>
+renderer.setAnimationLoop( function () {
+
+	renderer.render( scene, camera );
+
+} );
+	</code>
+
+	<h2>Next Steps</h2>
+
+	<p>
+		Have a look at one of the official WebVR examples to see this workflow in action.<br /><br />
+
+		[example:webvr_ballshooter WebVR / ballshoter]<br />
+		[example:webvr_cubes WebVR / cubes]<br />
+		[example:webvr_dragging WebVR / dragging]<br />
+		[example:webvr_lorenzattractor WebVR / lorenzattractor]<br />
+		[example:webvr_panorama WebVR / panorama]<br />
+		[example:webvr_paint WebVR / paint]<br />
+		[example:webvr_rollercoaster WebVR / rollercoaster]<br />
+		[example:webvr_sandbox WebVR / sandbox]<br />
+		[example:webvr_sculpt WebVR / sculpt]<br />

+		<h1>[name]</h1>
+
+		<p class="desc">
+			This article shows how to get three.js into a [link:https://nodejs.org/en/ node.js] environment so that you
+			can execute automated tests. Tests can be run on the command line, or by automated
+			CI tools like [link:https://travis-ci.org/ Travis].
+		</p>
+
+		<h2>The short version</h2>
+
+		<p>
+			If you're comfortable with node and npm,
+			<code>
+				$ npm install three --save-dev
+			</code>
+			and add
+		<code>
+			var THREE = require('three');
+		</code>
+			to your test.
+		</p>
+
+		<h2>Create a testable project from scratch</h2>
+		<p>
+			If you're not familiar with these tools, here's a quick guide (for linux, the installation process
+			will be slightly different using windows, but the NPM commands are identical).
+		</p>
+
+		<h3>Basic setup</h3>
+		<div>
+			<ol>
+				<li>
+					Install [link:https://www.npmjs.org/ npm] and nodejs. The shortest path typically looks something like
+					<code>
+$ sudo apt-get install -y npm nodejs-legacy
+# fix any problems with SSL in the default registry URL
+$ npm config set registry http://registry.npmjs.org/
+					</code>
+				</li>
+
+				<li>
+					Make a new project directory
+					<code>
+						 $ mkdir test-example; cd test-example
+					</code>
+				</li>
+
+				<li>
+					Ask npm to create a new project file for you:
+					<code>
+					 $ npm init
+					</code>
+					 and accept all defaults by hitting Enter on all the prompts.
+					 This will create package.json.
+				</li><br />
+
+				<li>
+					Try and start the test feature with
+					<code>
+$ npm test
+					</code>
+					This will fail, which is expected.
+					If you look in the package.json, the definition of the test script is
+					<code>
+						"test": "echo \"Error: no test specified\" && exit 1"
+					</code>
+				</li>
+
+			</ol>
+		</div>
+
+		<h2>Add mocha</h2>
+		<div>
+			We're going to use [link:https://mochajs.org/ mocha].
+
+			<ol>
+				<li>
+					Install mocha with
+					<code>
+$ npm install mocha --save-dev
+					</code>
+					Notice that node_modules/ is created and your dependencies appear in there.
+				  Also notice that your package.json has been updated: the property devDependencies
+					is added and updated by the use of --save-dev.
+				</li><br />
+
+				<li>
+					Edit package.json to use mocha for testing. When test is invoked, we just want to run
+					mocha and specify a verbose reporter. By default this will run anything in test/
+					(not having directory test/ can run into npm ERR!, create it by mkdir test)
+					<code>
+						"test": "mocha --reporter list"
+					</code>
+				</li>
+
+				<li>
+					Rerun the test with
+					<code>
+						$ npm test
+					</code>
+
+					This should now succeed, reporting 0 passing (1ms)
+				 	or similar.
+				</li>
+
+			</ol>
+		</div>
+
+		<h2>Add three.js</h2>
+		<div>
+			<ol>
+				<li>
+					Let's pull in our three.js dependency with
+					<code>
+$ npm install three --save-dev
+					</code>
+					<ul>
+						<li>
+							If you need a different three version, use
+							<code>
+								$ npm show three versions
+							</code>
+						  to see
+							what's available. To tell npm the right one, use
+							<code>
+ $ npm install three@0.84.0 --save
+							</code>
+							(0.84.0 in this example). --save makes this a dependency of this project, rather than
+							dev dependency. See the docs [link:https://www.npmjs.org/doc/json.html here] for more info.
+						</li>
+					</ul>
+				</li>
+
+				<li>
+					Mocha will look for tests in test/, so let's
+					<code>
+					$ mkdir test
+					</code>
+				</li>
+
+				<li>
+					Finally we actually need a JS test to run. Let's add a simple test that will verify that
+					the three.js object is available and working. Create test/verify-three.js containing:
+<code>
+var THREE = require('three');
+var assert = require("assert");
+
+describe('The THREE object', function() {
+  it('should have a defined BasicShadowMap constant', function() {
+    assert.notEqual('undefined', THREE.BasicShadowMap);
+  }),
+
+  it('should be able to construct a Vector3 with default of x=0', function() {
+    var vec3 = new THREE.Vector3();
+    assert.equal(0, vec3.x);
+  })
+})
+</code>
+				</li>
+
+				<li>
+				Finally let's test again with $ npm test. This should run the tests above and succeed,
+				showing something like:
+				<code>
+The THREE object should have a defined BasicShadowMap constant: 0ms
+The THREE object should be able to construct a Vector3 with default of x=0: 0ms
+2 passing (8ms)
+				</code>
+				</li>
+			</ol>
+		</div>
+
+		<h2>Add your own code</h2>
+		<div>
+			You need to do three things:
+
+			<ol>
+				<li>
+					Write a test for the expected behaviour of your code, and place it under test/.
+					[link:https://github.com/air/encounter/blob/master/test/Physics-test.js Here] is an example from a real project.
+				</li>
+
+				<li>
+					Export your functional code in such a way that nodejs can see it, for use in conjunction with require.
+					See it [link:https://github.com/air/encounter/blob/master/js/Physics.js here].
+				</li>
+
+				<li>
+					Require your code into the test file, in the same way we did a require('three') in the example above.
+				</li>
+			</ol>
+
+			<p>
+				Items 2 and 3 will vary depending on how you manage your code. In the example of Physics.js
+		  	given above, the export part is right at the end. We assign an object to module.exports:
+			</p>
+			<code>
+//=============================================================================
+// make available in nodejs
+//=============================================================================
+if (typeof exports !== 'undefined')
+{
+  module.exports = Physics;
+}
+			</code>
+		</div>
+
+		<h2>Dealing with dependencies</h2>
+		<div>
+			<p>
+				If you're already using something clever like require.js or browserify, skip this part.
+			</p>
+			<p>
+				Typically a three.js project is going to run in the browser. Module loading is hence done by
+				the browser executing a bunch of script tags. Your individual files don't have to worry
+				about dependencies. In a nodejs context however, there is no index.html binding everything
+				together, so you have to be explicit.
+			</p>
+			<p>
+				If you're exporting a module that depends on other files, you're going to have to tell node to load them.
+				Here is one approach:
+			</p>
+			<ol>
+				<li>
+					At the start of your module, check to see if you're in a nodejs environment.
+				</li>
+				<li>
+					If so, explicitly declare your dependencies.
+				</li>
+				<li>
+					If not, you're probably in a browser so you don't need to do anything else.
+				</li>
+			</ol>
+			Example code from Physics.js:
+			<code>
+//=============================================================================
+// setup for server-side testing
+//=============================================================================
+if (typeof require === 'function') // test for nodejs environment
+{
+  var THREE = require('three');
+  var MY3 = require('./MY3.js');
+}
+			</code>

+		<h1>[name]</h1>
+
+		<h2>Overview(概述)</h2>
+
+		<p class="desc">
+			在three.js动画系统中，您可以为模型的各种属性设置动画：
+			[page：SkinnedMesh 蒙皮和装配模型]的骨头，[page：Geometry.morphTargets 变形目标]，不同的材料属性（颜色，
+			不透明度，布尔运算），可见性和变换。 动画属性可以淡入，淡出，交叉淡化和扭曲。 不同时间的重量和时间尺度
+			可以更改同一对象以及不同对象上的动画独立。 可以在相同和不同对象上进行各种动画同步。
+			<br /><br />
+			在一个同构系统中实现所有这一切，即three.js动画系统
+			[link：https：//github.com/mrdoob/three.js/issues/6881在2015年彻底改变]
+			（注意过时的信息！），它现在有一个与Unity /虚幻引擎4类似的架构.此页面简要概述了主要组件系统以及它们如何协同工作。
+		</p>
+
+		<h3>Animation Clips(动画片段)</h3>
+
+		<p class="desc">
+			如果您已成功导入动画3D对象（如果有，则无关紧要）
+			骨骼或变形目标或两者） - 例如使用[link：https：//github.com/KhronosGroup/glTF-Blender-Exporter glTF Blender导出器]从Blender导出它
+			使用[page：GLTFLoader]将其加载到three.js场景中 - 其中一个响应字段应该是一个名为“animations”的数组，其中包含此模型的[page：AnimationClip AnimationClips]（请参阅下面的可能加载器列表）。
+			<br /><br />
+			每个* AnimationClip *通常保存对象的某个活动的数据。 如果
+			mesh是一个字符，例如，可以有一个用于walkcycle的动画片段，第二个
+			跳跃，三分之一的回避等等。		
+		</p>
+
+		<h3>Keyframe Tracks(关键帧轨道)</h3>
+
+		<p class="desc">
+			在这样的* AnimationClip *里面，每个动画属性的数据都存储在一个
+			单独[page：KeyframeTrack]。 假设一个角色对象有一个[page：Skeleton skeleton]，
+			一个关键帧轨道可以存储下臂骨骼位置变化的数据
+			随着时间的推移，不同的轨道数据为同一骨骼的旋转变化，三分之一
+			轨道位置，旋转或缩放另一个骨骼，等等。 应该很清楚，
+			AnimationClip可以由许多这样的轨道组成。
+			.<br /><br />
+			假设模型具有[page：Geometry.morphTargets 变形目标]（例如一个变形
+			目标显示一个友好的面孔，另一个显示愤怒的脸），每个轨道持有
+			关于某个变形的[page：Mesh.morphTargetInfluences 影响]的信息
+			目标在剪辑执行期间发生变化。
+		</p>
+
+		<h3>Animation Mixer(动画混音器)</h3>
+
+		<p class="desc">
+			存储的数据仅构成动画的基础 - 实际播放由控制
+			[page：AnimationMixer]。 你可以想象这不仅仅是动画的播放器，而是
+			作为硬件的模拟，如真正的调音台控制台，可以控制几个动画
+			同时，混合和合并它们。
+		</p>
+
+		<h3>Animation Actions</h3>
+
+		<p class="desc">
+			* AnimationMixer *本身只有很少（通用）属性和方法，因为它
+			可以通过[page：AnimationAction AnimationActions]来控制。 通过配置
+			* AnimationAction *您可以确定何时播放某个* AnimationClip *，暂停
+			或者停在其中一个混音器上，是否以及频率必须重复，无论是否
+			应使用淡入淡出或时间缩放以及一些其他内容（例如交叉渐变）来执行
+			或同步。
+		</p>
+
+		<h3>Animation Object Groups(动画对象组)</h3>
+
+		<p class="desc">
+				如果您希望一组对象接收共享动画状态，则可以使用[page:AnimationObjectGroup].
+
+		</p>
+
+		<h3>Supported Formats and Loaders(支持的格式和加载器)</h3>
+
+		<p class="desc">
+			请注意，并非所有模型格式都包含动画（尤其是OBJ，没有），而且只有一些
+			three.js加载器支持[page：AnimationClip AnimationClip]序列。 以下几个<i>确实</ i>
+			支持此动画类型：		
+		</p>
+
+			<ul>
+				<li>[page:JSONLoader THREE.JSONLoader]</li>
+				<li>[page:ObjectLoader THREE.ObjectLoader]</li>
+				<li>THREE.BVHLoader</li>
+				<li>THREE.ColladaLoader</li>
+				<li>THREE.FBXLoader</li>
+				<li>[page:GLTFLoader THREE.GLTFLoader]</li>
+				<li>THREE.MMDLoader</li>
+				<li>THREE.SEA3DLoader</li>
+			</ul>
+
+		<p class="desc">
+			请注意，3ds max和Maya当前无法导出多个动画（这意味着动画不是
+			在同一时间线上）直接到一个文件。
+		</p>
+
+		<h2>Example</h2>
+
+		<code>
+		var mesh;
+
+		// Create an AnimationMixer, and get the list of AnimationClip instances
+		var mixer = new THREE.AnimationMixer( mesh );
+		var clips = mesh.animations;
+
+		// Update the mixer on each frame
+		function update () {
+			mixer.update( deltaSeconds );
+		}
+
+		// Play a specific animation
+		var clip = THREE.AnimationClip.findByName( clips, 'dance' );
+		var action = mixer.clipAction( clip );
+		action.play();
+
+		// Play all animations
+		clips.forEach( function ( clip ) {
+			mixer.clipAction( clip ).play();
+		} );
+		</code>

+            在所有现代浏览器中，Three.js可以使用WebGL来渲染场景。对于较旧的浏览器，特别是Internet Explorer 10或者更低版本浏览器，你将需要回落到其它[link:https://github.com/mrdoob/three.js/tree/master/examples/js/renderers renderers]（CSS2DRenderer、CSS3DRenderer、SVGRenderer、CanvasRenderer）。此外，你或许不得不包含一些额外的“填充物”来解决兼容性问题，特别是当你使用[link:https://github.com/mrdoob/three.js/tree/master/examples /examples]目录中的文件时。
+		</p>
+		<p>
+            注意：如果你并不需要支持较旧的浏览器，那就不推荐使用其他渲染器来进行渲染，因为与WebGLRenderer相比，其它渲染器渲染较慢，并且不支持WebGL的诸多特性。

+		<h1>创建一个场景（[name]）</h1><br />
+
+		<p>这一部分将对three.js来做一个简要的介绍。在这一部分里，我们将以搭建一个包含有旋转立方体的场景。在页面下方有一个已经完成的例子，当你遇到麻烦，或者需要帮助的时候，可以看一看。</p>
+
+		<h2>开始之前</h2>
+		<p>
+			在你开始使用three.js之前，你需要一个地方来显示它。将下列HTML代码保存为你电脑上的一个HTML文件，同时将[link:https://threejs.org/build/three.js three.js]复制到该HTML文件所在的目录下的js/目录下，然后在你的浏览器中打开这个HTML文件。
+		</p>
+		<code>
+		&lt;!DOCTYPE html&gt;
+		&lt;html&gt;
+			&lt;head&gt;
+				&lt;meta charset=utf-8&gt;
+				&lt;title&gt;My first three.js app&lt;/title&gt;
+				&lt;style&gt;
+					body { margin: 0; }
+					canvas { width: 100%; height: 100% }
+				&lt;/style&gt;
+			&lt;/head&gt;
+			&lt;body&gt;
+				&lt;script src="js/three.js"&gt;&lt;/script&gt;
+				&lt;script&gt;
+					// Our Javascript will go here.
+				&lt;/script&gt;
+			&lt;/body&gt;
+		&lt;/html&gt;
+		</code>
+
+		<p>好了，接下来的所有代码将会写入到空的&lt;script&gt;标签中。</p>
+
+		<h2>创建一个场景</h2>
+
+		<p>为了真正能够让你的场景借助three.js来进行显示，我们需要以下几个对象：场景、相机和渲染器，这样我们就能透过摄像机渲染出场景。</p>
+
+		<code>
+		var scene = new THREE.Scene();
+		var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
+
+		var renderer = new THREE.WebGLRenderer();
+		renderer.setSize( window.innerWidth, window.innerHeight );
+		document.body.appendChild( renderer.domElement );
+		</code>
+
+		<p>我们花一点点时间来解释一下这里发生了什么。我们现在建立了场景、相机和渲染器。</p>
+
+		<p>three.js里有几种不同的相机，在这里，我们使用的是<strong>PerspectiveCamera</strong>（透视摄像机）。</p>
+
+		<p>第一个属性是<strong>视野角度（FOV）</strong>。视野角度就是无论在什么时候，你所能在显示器上看到的场景的范围，它的值是一个角度。</p>
+
+		<p>第二个值是<strong>长宽比（aspect ratio）</strong>。 也就是你用一个物体的宽除以它的高的比值。比如说，当你在一个宽屏电视上播放老电影时，可以看到图像仿佛是被压扁的。</p>
+
+		<p>接下来的两个值是<strong>远剪切面</strong>和<strong>近剪切面</strong>。 也就是说当物体所在的位置比摄像机的<strong>远剪切面</strong>远或者所在位置比<strong>近剪切面</strong>近的时候，该物体超出的部分将不会被渲染到场景中。现在你或许并不用担心这个值的影响，但未来为了获得更好的渲染性能，你将可以在你的应用程序里去设置它。</p>
+
+		<p>接下来是渲染器。这里是施展魔法的地方。除了我们在这里用到的WebGLRenderer渲染器之外，Three.js同时提供了其他几种渲染器，当用户所使用的浏览器过于老旧，或者由于其他原因不支持WebGL时，可以使用这几种渲染器进行降级。</p>
+
+		<p>除了创建一个渲染器的实例之外，我们还需要在我们的应用程序里设置一个渲染器的大小尺寸。比如说，我们可以使用所需要的渲染区域的宽高，来让渲染器渲染出的场景填充满我们的应用程序。因此，我们可以将渲染器宽高设置为浏览器窗口宽高。对于性能比较敏感的应用程序来说，你可以给<strong>setSize</strong>传入一个较小的值，例如<strong>window.innerWidth/2</strong>和<strong>window.innerHeight/2</strong>，这将使得应用程序在渲染时，以一半的长宽尺寸渲染场景。</p>
+
+		<p>如果你希望保持你的应用程序的尺寸，但是以较低的分辨率来渲染，你可以在调用<strong>setSize</strong>时，给<strong>updateStyle</strong>（第三个参数）传入false。例如，假设你的&lt;canvas&gt; 标签现在已经具有了100%的宽和高，调用<strong>setSize(window.innerWidth/2, window.innerHeight/2, false)</strong>将使得你的应用程序以一半的分辨率来进行渲染。</p>
+
+		<p>最后，我们将<strong>renderer</strong>（渲染器）这个元素添加到我们的HTML文档中，这也就是渲染器使用&lt;canvas&gt;元素来将场景展现给我们。</p>
+
+		<p><em>“嗯，看起来很不错，那你说的那个立方体在哪儿？”</em>我们接下来来对它继续进行添加吧。</p>
+
+		<code>
+		var geometry = new THREE.BoxGeometry( 1, 1, 1 );
+		var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
+		var cube = new THREE.Mesh( geometry, material );
+		scene.add( cube );
+
+		camera.position.z = 5;
+		</code>
+
+		<p>要创建一个立方体，我们需要一个<strong>BoxGeometry</strong>（立方体）对象. 这个对象包含了一个立方体中所有的顶点（<strong>vertices</strong>）和面<strong>faces</strong>。未来我们将在这方面进行更多的探索。</p>
+
+		<p>接下来，对于这个立方体，我们需要给它一个材质，来让它有颜色。Three.js自带了几种材质，但在这里我们使用的是<strong>MeshBasicMaterial</strong>。所有的材质是都一个将会被应用于立方体的属性对象。在这里为了简单起见,我们只设置一个color属性，值为<strong>0x00ff00</strong>，也就是绿色。这里所做的事情，就相当于是在CSS或者Photoshop中使用十六进制(<strong>hex colors</strong>)的颜色格式来设置颜色。</p>
+
+		<p>第三步，我们需要一个<strong>Mesh</strong>（网格）。 网格是包含有一个几何体以及应用在在此几何体上的材质的对象，我们可以直接将网格对象放入到我们的场景中，并让它在场景中自由移动。</p>
+
+		<p>默认情况下，当我们调用<strong>scene.add()</strong>的时候，物体将会被添加到坐标为<strong>(0,0,0)</strong>的位置。但这可能会使得摄像机的位置和立方体相互重叠（也就是摄像机位于立方体中）。为了防止这种情况的发生，我们只需要将摄像机稍微向外移动一些即可。</p>
+
+		<h2>渲染场景</h2>
+
+		<p>现在，如果你已经从上面复制了我们已经写好的代码到HTML文件中，你将不会在其中看到任何东西。这是因为我们还没有对它进行真正的渲染。为此，我们需要调用一个被叫做“<strong>渲染</strong>”或者“<strong>动画循环</strong>”的东西。</p>
+
+		<code>
+		function animate() {
+			requestAnimationFrame( animate );
+			renderer.render( scene, camera );
+		}
+		animate();
+		</code>
+
+		<p>在这里我们创建了一个循环——这使得渲染器能够在每次屏幕刷新时对场景进行绘制（在大多数屏幕上，刷新率一般是60次/秒）。如果你正在浏览器里写一个游戏，你或许会说<em>“为什么我们不直接用setInterval来实现刷新的功能呢？”</em>当然啦，我们的确可以用setInterval，但是，<strong>requestAnimationFrame</strong>有很多的优点。最重要的一点或许就是当用户切换到其它的标签页时，它会暂停，因此不会浪费用户宝贵的处理器资源，以及损耗电池的使用寿命。</p>
+
+		<h2>使立方体动起来</h2>
+
+		<p>
+			在开始之前，如果你已经将上面的代码写入到了你所创建的文件中，你应当已经可以看到一个绿色的立方体。让我们来做一些更加有趣的事——让它旋转起来。</p>
+
+		<p>将下列代码添加到animate()函数中<strong>renderer.render</strong>调用的上方：</p>
+
+		<code>
+		cube.rotation.x += 0.01;
+		cube.rotation.y += 0.01;
+		</code>
+
+		<p>这一段代码将在每一帧时被渲染时调用（正常情况下是60次/秒），这就让立方体有了一个看起来很不错的旋转动画。基本上来说，当应用程序运行时，如果你想要移动或者改变任何场景中的东西，都必须要经过这个动画循环。当然，在这个动画循环函数里，你也可以调用别的函数，这样你在写<strong>animate</strong>函数的时候，这样你在写animate函数的时候，就不用在这里以成千上万的代码来结尾了。</p>
+
+		<h2>结果</h2>
+		<p>祝贺你！你现在已经成功完成了你的第一个Three.js应用程序。它现在很简单, 你现在已经有了一个起点。</p>
+
+		<p>下面是完整的代码，请尽情运行它或者修改它，这将可以让你对它的工作机制有更加深入的了解。</p>
+

+		<h1>创建文字（[name]）</h1>
+		<div>
+			<p>有时候，您可能需要在你的Three.js应用程序中使用到文本，这里有几种方法可以做到。
+			</p>
+		</div>
+
+		<h2>1. DOM + CSS</h2>
+		<div>
+			<p>
+				使用HTML通常是最简单、最快速的添加文本的方法，这是大多数的Three.js示例中用于添加描述性叠加文字的方法。
+			</p>
+			<p>你可以在这里添加内容</p>
+			<code>&lt;div id="info"&gt;Description&lt;/div&gt;</code>
+
+			<p>
+				然后使用CSS来将其绝对定位在其它具有z-index的元素之上，尤其是当你全屏运行three.js的时候。
+			</p>
+
+			<code>
+#info {
+	position: absolute;
+	top: 10px;
+	width: 100%;
+	text-align: center;
+	z-index: 100;
+	display:block;
+}
+			</code>
+
+		</div>
+
+
+
+		<h2>2. 将文字绘制到画布中，并将其用作[page:Texture]（纹理）</h2>
+		<div>
+			<p>如果你希望在three.js的场景中的平面上轻松地绘制文本，请使用此方法。</p>
+		</div>
+
+
+		<h2>3. 在你所喜欢的3D软件里创建模型，并导出给three.js
+			 </h2>
+		<div>
+			<p>如果你更喜欢使用3D建模软件来工作并导出模型到three.js，请使用这种方法。</p>
+		</div>
+
+
+
+		<h2>4. three.js自带的文字几何体</h2>
+		<div>
+			<p>
+				如果你更喜欢使用纯three.js来工作，或者创建能够由程序改变的、动态的3D文字，你可以创建一个其几何体为THREE.TextGeometry的实例的网格：
+			</p>
+			<p>
+				<code>new THREE.TextGeometry( text, parameters );</code>
+			</p>
+			<p>
+				然而，为了使得它能够工作，你的TextGeometry需要在其“font”参数上设置一个THREE.Font的实例。
+<br>
+				请参阅 [page:TextGeometry] 页面来阅读如何完成此操作的详细信息，以及每一个接收的参数的描述，还有由three.js分发、自带的JSON字体的列表。
+			</p>
+
+			<h3>示例</h3>
+			[example:webgl_geometry_text WebGL / geometry / text]<br />
+			[example:canvas_geometry_text canvas / geometry / text]<br />
+			[example:webgl_shadowmap WebGL / shadowmap]
+
+			<p>
+				如果Typeface已经关闭，或者没有你所想使用的字体，这有一个教程:[link:http://www.jaanga.com/2012/03/blender-to-threejs-create-3d-text-with.html]<br>
+				这是一个在blender上运行的python脚本，能够让你将文字导出为Three.js的JSON格式。
+				</p>
+
+		</div>
+
+
+
+		<h2>5. 位图字体</h2>
+		<div>
+			<p>
+				BMFonts (位图字体) 可以将字形批处理为单个BufferGeometry。BMFont的渲染支持自动换行、字母间距、字句调整、signed distance fields with standard derivatives、multi-channel signed distance fields、多纹理字体等特性。
+				详情请参阅[link:https://github.com/Jam3/three-bmfont-text three-bmfont-text]。
+			</p>
+			<p>
+				现有库存的字体在项目中同样可用，就像[link:https://github.com/etiennepinchon/aframe-fonts A-Frame Fonts]一样，
+				或者你也可以从任何TTF字体中创建你自己的字体，优化时，只需要包含项目中所需的字符即可。
+			</p>
+			<p>
+				这是一些有用的工具：
+			</p>
+			<ul>
+				<li>[link:http://msdf-bmfont.donmccurdy.com/ msdf-bmfont-web] <i>(web-based)</i></li>
+				<li>[link:https://github.com/soimy/msdf-bmfont-xml msdf-bmfont-xml] <i>(commandline)</i></li>

+		<h1>画线（[name]）</h1>
+		<div>
+			<p>
+				假设你将要画一个圆或者画一条线，而不是一个线框，或者说不是一个[page:Mesh]（网格）。
+				第一步我们要做的，是设置好[page:WebGLRenderer renderer]（渲染器）、[page:Scene scene]（场景）和[page:Camera camera]（相机）-（如果对这里所提到的东西，还不了解，请阅读本手册第一章“创建一个场景 - Creating a scene”）。
+			</p>
+
+			<p>这是我们将要用到的代码：</p>
+			<code>
+var renderer = new THREE.WebGLRenderer();
+renderer.setSize( window.innerWidth, window.innerHeight );
+document.body.appendChild( renderer.domElement );
+
+var camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 );
+camera.position.set( 0, 0, 100 );
+camera.lookAt( 0, 0, 0 );
+
+var scene = new THREE.Scene();
+			</code>
+			<p>
+				接下来我们要做的事情是定义一个材质。对于线条来说，我们能使用的材质只有[page:LineBasicMaterial] 或者 [page:LineDashedMaterial]。
+			</p>
+			<code>
+//create a blue LineBasicMaterial
+var material = new THREE.LineBasicMaterial( { color: 0x0000ff } );
+			</code>
+
+			<p>
+				定义好材质之后，我们需要一个带有一些顶点的[page:Geometry] 或者 [page:BufferGeometry]。
+				（推荐使用BufferGeometry，因为它在性能上表现得会更好一些；但在这里，为了简单起见，我们使用Geometry）：
+			</p>
+
+			<code>
+var geometry = new THREE.Geometry();
+geometry.vertices.push(new THREE.Vector3( -10, 0, 0) );
+geometry.vertices.push(new THREE.Vector3( 0, 10, 0) );
+geometry.vertices.push(new THREE.Vector3( 10, 0, 0) );
+			</code>
+
+			<p>注意，线是画在每一对连续的顶点之间的，而不是在第一个顶点和最后一个顶点之间绘制线条（线条并未闭合）。</p>
+
+			<p>既然我们已经有了能够画两条线的点和一个材质，那我们现在就可以将他们组合在一起，形成一条线。</p>
+			<code>
+var line = new THREE.Line( geometry, material );
+			</code>
+			<p>剩下的事情就是把它添加到场景中，并调用[page:WebGLRenderer.render render]（渲染）函数。</p>
+
+			<code>
+scene.add( line );
+renderer.render( scene, camera );
+			</code>
+
+			<p>你现在应当已经看到了一个由两条蓝线组成的、指向上的箭头。</p>

+		<h1>常见问题（[name]）</h1>
+
+		<h2>哪一种三维物体格式能够得到最好地支持呢？</h2>
+		<div>
+			<p>
+			推荐使用glTF（gl传输格式）来对三维物体进行导入和导出，由于glTF这种格式是专注于在程序运行时呈现三维物体的，所以它的传输效率非常高，且加载速度非常快。
+			</p>
+			
+			
+			<p>three.js同样也为其它广受欢迎的格式像FBX、Collada以及OBJ等等提供了载入工具。虽然如此，你应当还是首先尝试着在你的项目里建立一个基于glTF的工作流程。
+				了解更多详细信息，请查看[link:#manual/introduction/Loading-3D-models loading 3D models]。
+			</p>
+		</div>
+
+		<h2>为什么在示例中会有一些和viewport相关的meta标签？</h2>
+		<div>
+			<div class="highlight highlight-text-html-basic"><pre>&lt;<span class="pl-ent">meta</span> <span class="pl-e">name</span>=<span class="pl-s"><span class="pl-pds">"</span>viewport<span class="pl-pds">"</span></span> <span class="pl-e">content</span>=<span class="pl-s"><span class="pl-pds">"</span>width=device-width, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0<span class="pl-pds">"</span></span>&gt;</pre></div>
+
+				<p>这些标签用于在移动端浏览器上控制视口的大小和缩放（页面内容可能会以与可视区域不同的大小来呈现）。</p>
+
+				<p>[link:https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/UsingtheViewport/UsingtheViewport.html Safari: Using the Viewport]</p>
+
+				<p>[link:https://developer.mozilla.org/en/Mobile/Viewport_meta_tag MDN: Using the viewport meta tag]</p>
+		</div>
+
+		<h2>如何在窗口调整大小时保持场景比例不变？</h2>
+		<p>
+			我们希望所有的物体，无论它们距离摄像机有多远，都能呈现相同尺寸，即使是在窗口被重新调整大小的时候。
+			解决这个问题的关键，是一个很重要的公式：给定距离，求可见高度
+			<code>
+visible_height = 2 * Math.tan( ( Math.PI / 180 ) * camera.fov / 2 ) * distance_from_camera;<br>
+			</code>
+			如果我们以一定的百分比增加了窗口的高度，那我们所想要的结果便是所有距离的可见高度都增加相同的百分比。
+			这并不能通过改变摄像机的位置来实现，相反，你得改变摄像机的视野角度（FOV）。这是个示例：[link:http://jsfiddle.net/Q4Jpu/ Example].
+		</p>
+
+		<h2>为什么我的物体的一部分是不可见的？</h2>
+		<p>
+			这可能是由于面消隐而导致的。面是具有朝向的，这个朝向决定了哪边是正面或者哪边是背面。
+			在正常情况下，渲染时会将背面进行消隐。要查看这是不是你所遇到的问题，请将material的slide更改为THREE.DoubleSide。
+			<code>material.side = THREE.DoubleSide</code>

+		<h1>如何在本地运行Three.js（[name]）</h1>
+		<p>
+            倘若你只是使用Three.js库中所提供的几何体，且不载入任何纹理贴图，则网页是可以从本地的文件系统中打开，并且是能够直接运行的，只需在文件管理器中双击HTML文件，它就可以在浏览器中进行显示。
+            （此时你将在地址栏中看到类似这样的URL：<em>file:///yourFile.html</em>）
+			
+		</p>
+
+		<h2>从外部文件载入的内容</h2>
+		<div>
+			<p>
+                倘若你需要从外部文件里载入几何体或是纹理贴图，由于浏览器[link:http://en.wikipedia.org/wiki/Same_origin_policy same origin policy]（同源策略）的安全限制，从本地文件系统载入外部文件将会失败，同时抛出安全性异常。
+		 	</p>
+
+			<p>这里有两种方法来解决这个问题：</p>
+
+			<ol>
+				<li>
+                    在浏览器中改变本地文件的安全策略，这将使你可以通过<code>file:///yourFile.html</code>来直接运行*本地文件系统*中的文件。
+				</li>
+				<li>
+                    从本地的服务器运行文件，这可以让你通过<code>http://localhost/yourFile.html</code>来访问运行在*本地服务器*上的文件。
+				</li>
+			</ol>
+
+			<p>
+                倘若你选择第一种方法，请小心，倘若你使用同一个浏览器来进行日常网络冲浪，你将可能会触发一些漏洞。
+                你或许可以创建一个用于开发环境的独立的浏览器配置文件或者快捷方式，仅仅用于本地开发；这将使得日常使用环境与开发环境相分离，以保证日常使用环境的安全性。
+                接下来，我们来看一看除此之外的别的方法。
+			</p>
+		</div>
+
+
+		<h2>运行一个本地的服务器</h2>
+		<div>
+			<p>
+                很多的编程语言都具有一个内置的简易HTTP服务器。它们的功能并不像能够被用于生产环境的服务器，例如[link:https://www.apache.org/ Apache] 或者 [link:https://nginx.org NGINX]那样完善，
+                但对于你来测试three.js应用程序来说，它们就已经足够了。
+			</p>
+
+			<h3>Node.js server</h3>
+			<div>
+				<p>Node.js 具有一个简单的HTTP服务器包，如需安装，请执行：</p>
+				<code>npm install http-server -g</code>
+
+				<p>若要从本地目录下运行，请执行：</p>
+				<code>http-server . -p 8000</code>
+			</div>
+
+			<h3>Python server</h3>
+			<div>
+				<p>
+					如果你已经安装好了[link:http://python.org/ Python]，只需要从命令行里便可以运行它（从工作目录）：
+				</p>
+				<code>
+//Python 2.x
+python -m SimpleHTTPServer
+
+//Python 3.x
+python -m http.server
+				</code>
+
+				<p>这将会在为当前目录在8000端口创建一个服务器，也就是说你可以在地址栏里输入这个地址来访问已经创建好的服务器：</p>
+
+				<code>http://localhost:8000/</code>
+			</div>
+
+			<h3>Ruby server</h3>
+			<div>
+				<p>如果你已经安装好了Ruby，通过执行下列命也可以创建同样的服务器：</p>
+				<code>
+ruby -r webrick -e "s = WEBrick::HTTPServer.new(:Port => 8000, :DocumentRoot => Dir.pwd); trap('INT') { s.shutdown }; s.start"
+				</code>
+			</div>
+
+			<h3>PHP server</h3>
+			<div>
+				<p>PHP自从5.4.0版本开始，就内置了一个Web服务器：</p>
+				<code>php -S localhost:8000</code>
+			</div>
+
+			<h3>Lighttpd</h3>
+			<div>
+				<p>
+                    Lighttpd是一个轻量级的通用Web服务器，在这里，我们将介绍如何在OS X上使用HomeBrew来安装它。
+                    和我们在这里讨论的其他服务器不同，lighttpd是一个成熟的、准用于生产环境的服务器。
+				</p>
+
+				<ol>
+					<li>
+						通过HomeBrew安装lighttpd

+		<h2>更改本地文件的安全策略</h2>
+		<div>
+			<h3>Safari</h3>
+			<div>
+				<p>
+                    在“偏好”面板中启用开发菜单，位于“高级”-&gt“在菜单栏中显示开发菜单”
+				</p>
+
+				<p>
+                    之后从Safari中的“开发”菜单中，选择“停用本地文件限制”，同样需要注意的是，Safari对于缓存有一些奇怪的行为，
+                    因此建议，在同一菜单中打开“停用缓存”的选项；如果你正在编辑，请使用Safari进行调试。
+				</p>
+			</div>
+
+
+			<h3>Chrome</h3>
+			<div>
+				<p>请关闭Chrome浏览器正在运行的*所有*实例，注意这里非常重要的关键字是“*所有*”。</p>
+
+				<p>
+                    在Windows中，你可以在任务管理器中查看所有正在运行的Chorme浏览器的实例。
+                    此外，如果你在系统任务栏中看到了Chrome图标，请鼠标右键打开它的上下文菜单，点击关闭。这样就应当已经关闭所有正在运行的Chrome浏览器实例了。
+
+				</p>
+
+				<p>
+                    然后使用命令行执行Chrome浏览器，并在命令行中添加允许访问本地文件的参数：</p>
+
+				<code>chrome --allow-file-access-from-files</code>
+
+				<p>
+                    在Windows中，最简单的做法或许就是创建一个特别的快捷方式图标，快捷方式的目标指向上面的命令行
+                    （右键点击快捷方式图标-&gt;属性-&gt;目标）。
+				</p>
+
+				<p>在Mac OS X中，你可以用这种方法来添加允许访问本地文件的参数并运行Chrome：</p>
+
+				<code>open /Applications/Google\ Chrome.app --args --allow-file-access-from-files</code>
+			</div>
+			<h3>Firefox</h3>
+			<div>
+				<ol>
+				<li>
+					在地址栏中，键入<code>about:config</code>
+				</li>
+				<li>
+					找到这个参数<code>security.fileuri.strict_origin_policy</code>
+				</li>
+				<li>
+					将其设置为<em>false</em>
+				</li>
+				</ol>
+			</div>
+

+
+		<h2>Geometries(几何形状)</h2>
+		<div>
+			<h3>[page:BufferGeometry]</h3>
+			<div>
+				<p>
+					BufferGeometries 将信息（例如顶点位置，面索引，法线，颜色，uv和任何自定义属性） 存储在 [page:BufferAttribute buffers] - 也就是,
+					[link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays typed arrays].
+					这使得它们通常比标准Geometries更快，缺点是更难用。
+				</p>
+				<p>
+					关于更新BufferGeometries, 最重要的是理解你不能调整 buffers 大小(这种操作开销很大,	相当于创建了个新的geometry).
+					但你可以更新 buffers的内容.
+				</p>
+				<p>
+					这意味着如果你知道BufferGeometry的一个属性会增长，比如顶点的数量，
+					你必须预先分配足够大的buffer来容纳可能创建的任何新顶点。
+					当然，这也意味着BufferGeometry将有一个最大大小 - 无法创建一个可以高效地无限扩展的BufferGeometry。
+				</p>
+				<p>
+					我们以在渲染时扩展的line来示例。我们将分配可容纳500个顶点的空间但起初仅绘制2个，使用
+					在500个顶点的缓冲区中，但首先只使用 [page:BufferGeometry.drawRange].
+				</p>
+				<code>
+var MAX_POINTS = 500;
+
+// geometry
+var geometry = new THREE.BufferGeometry();
+
+// attributes
+var positions = new Float32Array( MAX_POINTS * 3 ); // 3 vertices per point
+geometry.addAttribute( 'position', new THREE.BufferAttribute( positions, 3 ) );
+
+// draw range
+var drawCount = 2; // draw the first 2 points, only
+geometry.setDrawRange( 0, drawCount );
+
+// material
+var material = new THREE.LineBasicMaterial( { color: 0xff0000, linewidth: 2 } );
+
+// line
+var line = new THREE.Line( geometry,  material );
+scene.add( line );
+				</code>
+			 	<p>
+					然后我们随机增加顶点到line中，以这样的一种方式：
+				</p>
+				<code>
+var positions = line.geometry.attributes.position.array;
+
+var x, y, z, index;
+x = y = z = index = 0;
+
+for ( var i = 0, l = MAX_POINTS; i < l; i ++ ) {
+
+    positions[ index ++ ] = x;
+    positions[ index ++ ] = y;
+    positions[ index ++ ] = z;
+
+    x += ( Math.random() - 0.5 ) * 30;
+    y += ( Math.random() - 0.5 ) * 30;
+    z += ( Math.random() - 0.5 ) * 30;
+
+}
+				</code>
+				<p>
+					如果要更改第一次渲染后渲染的<em>点数</em>，执行以下操作：
+				</p>
+				<code>
+line.geometry.setDrawRange( 0, newValue );
+				</code>
+				<p>
+					如果要在第一次渲染后更改position数值，则需要像这样设置needsUpdate标志：
+				</p>
+				<code>
+line.geometry.attributes.position.needsUpdate = true; // required after the first render
+				</code>
+
+				<p>
+					[link:http://jsfiddle.net/w67tzfhx/ 这个fiddle] 展示了一个你可以参考的运动的line.
+				</p>
+
+				<h3>Examples:</h3>
+					[example:webgl_custom_attributes WebGL / custom / attributes]<br />
+					[example:webgl_buffergeometry_custom_attributes_particles WebGL / buffergeometry / custom / attributes / particles]
+
+
+			</div>
+
+			<h3>[page:Geometry]</h3>
+			<div>
+				<p>
+					以下标志控制各种geometry属性的更新. 仅对于需要更新的属性设置标志
+					，因为更新成本很高. 一旦buffers
+					改变, 这些标志位会自动重置为false. 你需要保持这些设置为true,如果你想要持续更新buffers. 请注意这仅适用于[page:Geometry]
+					而不是 [page:BufferGeometry].
+				</p>
+				<code>
+var geometry = new THREE.Geometry();
+geometry.verticesNeedUpdate = true;
+geometry.elementsNeedUpdate = true;
+geometry.morphTargetsNeedUpdate = true;
+geometry.uvsNeedUpdate = true;
+geometry.normalsNeedUpdate = true;
+geometry.colorsNeedUpdate = true;
+geometry.tangentsNeedUpdate = true;
+				</code>
+
+				<p>
+					在早于 [link:https://github.com/mrdoob/three.js/releases/tag/r66 r66]版本中， meshes
+					需要额外设定 <em>dynamic</em> 标志true (为了维持内部的 typed arrays):
+				</p>

+		//removed after r66
+		geometry.dynamic = true;
+				</code>
+
+				<h3>Examples:</h3>
+					[example:webgl_geometry_dynamic WebGL / geometry / dynamic]<br />

+
+		</div>
+
+
+
+
+		<h2>Materials(材质)</h2>
+		<div>
+			<p>所有uniforms值都可以自由改变 (e.g. colors, textures, opacity, etc), 这些数值在每帧都发给shader .</p>
+
+			<p>GL状态相关参数也可以随时改变 (depthTest, blending, polygonOffset, etc).</p>
+
+			<p>平滑/平滑阴影被作到法线. 你需要重置法线 buffer (见上).</p>
+
+			<p>在运行时无法轻松更改以下属性 (一旦material被渲染了一次):</p>
+			<ul>
+				<li>uniforms的数量和类型</li>
+				<li>lights的数量和类型</li>
+				<li>存在与否
+					<ul>
+						<li>texture</li>

+						<li>morphing</li>
+						<li>shadow map</li>
+						<li>alpha test</li>
+					</ul>
+				</li>
+			</ul>
+
+			<p>这些变化需要建立新的shader程序. 你需要设置</p>
+			<code>material.needsUpdate = true</code>
+
+			<p>请记住，这可能会非常缓慢并导致帧率的波动。 (特别是在Windows上，因为shader编译在directx中比opengl慢).</p>
+
+			<p>为了获得更流畅的体验，您可以通过“虚拟”值（如零强度光，白色纹理或零密度雾）在一定程度上模拟这些功能的变化.</p>
+
+			<p>您可以自由更改用于几何块的材质，但是无法更改对象如何划分为块（根据面材料）. </p>
+
+			<h3>如果你需要在运行时使用不同的材料配置：</h3>
+			<p>如果材料/块的数量很少，您可以事先预先划分物体（例如，人的头发/脸部/身体/上衣/裤子，汽车的前部/侧面/顶部/玻璃/轮胎/内部）. </p>
+
+			<p>如果数量很大（例如，每个面可能有所不同），请考虑不同的解决方案，例如使用属性/纹理来驱动不同的每个面部外观。</p>
+
+			<h3>Examples:</h3>
+			[example:webgl_materials_cars WebGL / materials / cars]<br />
+			[example:webgl_postprocessing_dof WebGL / webgl_postprocessing / dof]
+		</div>
+
+
+		<h2>Textures(纹理)</h2>
+		<div>
+			<p>如果更改了图像，画布，视频和数据纹理，则需要设置以下标志：</p>
+			<code>
+				texture.needsUpdate = true;
+			</code>
+			<p>Render targets update automatically.</p>
+
+			<h3>Examples:</h3>
+			[example:webgl_materials_video WebGL / materials / video]<br />

+		<h1>通过模块来引入（[name]）</h1><br />
+
+		<p>
+			虽然通过script标签来引入three.js是一个能够快速起步、快速运行的方式，但这种方式对于一些具有较长生命周期的项目来说是有一些缺点的。比如说：
+
+			<ul>
+				<li>你必须手动获得并在你的源代码中包含这个库的一个拷贝</li>
+				<li>更新这个库的版本是一个手动操作的过程</li>
+				<li>在检查新版本的库时，你的版本差异对比将会被许多行给弄乱。</li>
+			</ul>
+		</p>
+
+		<p>使用像npm这样的依赖包管理器可以很好地避免这些需要注意的问题，只需在你的电脑上下载并导入你所需要的库的版本即可。</p>
+
+		<h2>通过npm来安装</h2>
+
+		<p>Three.js目前已经作为一个npm包来进行了发布，详情请参阅：[link:https://www.npmjs.com/package/three npm]。这意味着，在所有你需要包含three.js库的项目中，只需运行"npm install three"即可。</p>
+
+		<h2>导入这个模块</h2>
+
+		<p>假设你正在使用[link:https://webpack.github.io/ Webpack]或者[link:https://github.com/substack/node-browserify Browserify]等允许你“通过打包所有依赖，来在浏览器中使用require('modules')”的打包工具对你的文件进行打包。</p>
+
+		<p>你现在可以在你的源代码中引入模块，并继续像往常一样使用这个库。
+		</p>
+
+		<code>
+		var THREE = require('three');
+
+		var scene = new THREE.Scene();
+		...
+		</code>
+
+		<p>
+			你也可以使用[link:https://developer.mozilla.org/zh-CN/docs/Web/JavaScript/Reference/Statements/import ES6 import]（在ES6标准中新增的import语句）
+		</p>
+
+		<code>
+		import * as THREE from 'three';
+
+		const scene = new THREE.Scene();
+		...
+		</code>
+
+		<p>
+			或者，如果你希望只导入three.js库中的特定部分，例如Scene：
+		</p>
+
+		<code>
+		import { Scene } from 'three';
+
+		const scene = new Scene();
+		...
+		</code>
+
+		<h2>注意事项</h2>
+
+		<p>
+			目前，无法用这种方式导入"examples/js"目录中的文件。
+			这是因为一些文件依赖于THREE的全局命名空间污染。了解更多详情，请参阅<a href="https://github.com/mrdoob/three.js/issues/9562" target="_blank">Transform `examples/js` to support modules #9562</a>。

+  <h1>载入3D模型（[name]）</h1>
+  <br />
+
+  <p>
+	3D模型目前的有成千上万种格式可供选择，但每一种格式都具有不同的目的、用途以及复杂性。
+    虽然<a href="https://github.com/mrdoob/three.js/tree/dev/examples/js/loaders" target="_blank" rel="noopener">
+	three.js已经提供了多种导入工具</a>
+	但是选择正确的文件格式以及工作流程将可以节省很多时间，以及避免很多挫折。某些格式难以使用，或者实时体验效率低下，或者目前尚未得到完全支持。
+  </p>
+
+  <p>
+		对大多数用户，本指南向你推荐了一个工作流程，并向你提供了一些当没有达到预期效果时的建议。
+
+  </p>
+
+  <h2>在开始之前</h2>
+
+  <p>
+	  如果你是第一次运行一个本地服务器，可以先阅读[link:#manual/introduction/How-to-run-things-locally how to run things locally]。
+	  正确地托管文件，可以避免很多查看3D模型时的常见错误。
+  </p>
+
+  <h2>推荐的工作流程</h2>
+
+  <p>
+	  如果有可能的话，我们推荐使用glTF（gl传输格式）。<small>.GLB</small>和<small>.GLTF</small>是这种格式的这两种不同版本，
+	  都可以被很好地支持。由于glTF这种格式是专注于在程序运行时呈现三维物体的，所以它的传输效率非常高，且加载速度非常快。
+	  功能方面则包括了网格、材质、纹理、皮肤、骨骼、变形目标、动画、灯光和摄像机。
+  </p>
+
+  <p>
+	  公共领域的glTF文件可以在网上找到，例如
+    <a href="https://sketchfab.com/models?features=downloadable&sort_by=-likeCount&type=models" target="_blank" rel="noopener">
+    Sketchfab</a>，或者很多工具包含了glTF的导出功能：
+  </p>
+
+  <ul>
+    <li><a href="https://github.com/KhronosGroup/glTF-Blender-Exporter" target="_blank" rel="noopener">glTF-Blender-Exporter</a> by the Khronos Group</li>
+    <li><a href="https://github.com/KhronosGroup/COLLADA2GLTF" target="_blank" rel="noopener">COLLADA2GLTF</a> by the Khronos Group</li>
+    <li><a href="https://github.com/facebookincubator/FBX2glTF" target="_blank" rel="noopener">FBX2GLTF</a> by Facebook</li>
+    <li><a href="https://github.com/AnalyticalGraphicsInc/obj2gltf" target="_blank" rel="noopener">OBJ2GLTF</a> by Analytical Graphics Inc</li>
+    <li><a href="https://www.allegorithmic.com/products/substance-painter" target="_blank" rel="noopener">Substance Painter</a> by Allegorithmic</li>
+    <li><a href="https://www.foundry.com/products/modo" target="_blank" rel="noopener">Modo</a> by Foundry</li>
+    <li><a href="https://www.marmoset.co/toolbag/" target="_blank" rel="noopener">Toolbag</a> by Marmoset</li>
+    <li>……<a href="https://github.com/khronosgroup/gltf#gltf-tools" target="_blank" rel="noopener">还有更多</a></li>
+  </ul>
+
+  <p>
+	  倘若你所喜欢的工具不支持glTF格式，请考虑向该工具的作者请求glTF导出功能，
+	  或者在<a href="https://github.com/KhronosGroup/glTF/issues/1051" target="_blank" rel="noopener">the glTF roadmap thread</a>贴出你的想法。
+
+  </p>
+
+  <p>
+	  当glTF不可用的时候，诸如FBX、OBJ或者COLLADA等等其它广受欢迎的格式在Three.js中也是可以使用、并且定期维护的。
+  </p>
+
+  <h2>故障排除</h2>
+
+  <p>
+	  你花了几个小时亲手建了一个堪称杰作的模型，现在你把它给导入到网页中——
+	  哦，天呐~😭它导入以后完全失真了、材质贴图丢了、或者说整个模型完全丢失了！<br>
+	  接下来我们来按照下面的步骤排除故障：
+  </p>
+
+  <ol>
+    <li>
+		在Javascript的Console中查找错误，并确定当你调用<em>.load()</em>的时候，使用了<em>onError</em>回调函数来输出结果。
+    </li>
+    <li>
+		请在别的应用程序中查看3D模型。对于glTF格式的模型来说，可以直接在下面的应用程序中进行查看：
+      <a href="https://gltf-viewer.donmccurdy.com/" target="_blank" rel="noopener">three.js</a>和
+	  <a href="http://sandbox.babylonjs.com/" target="_blank" rel="noopener">babylon.js</a>。
+	 如果该模型能够在一个或者更多应用程序里正确地呈现，请<a href="https://github.com/mrdoob/three.js/issues/new" target="_blank" rel="noopener">点击这里向three.js提交Bug报告</a>。
+	 如果模型不能在任意一个应用程序里显示，我们强烈鼓励你向我们提交Bug报告，并告知我们你的模型是使用哪一款应用程序创建的。
+
+    </li>
+    <li>
+		尝试将模型放大或缩小到原来的1000倍。许多模型的缩放比例各不相同，倘若摄像机位于相机内，则大型模型将可能不会显示。
+    </li>
+    <li>
+		在网络面板中查找失败的纹理贴图请求，像<em>C:\\Path\To\Model\texture.jpg</em>。使用相对于你的模型的文件路径，例如
+		<em>images/texture.jpg</em>——这或许需要在文本编辑器中来对模型文件进行修改。
+    </li>
+  </ol>
+
+  <h2>请求帮助</h2>
+
+  <p>
+	倘若你已经尝试经历了以上故障排除的过程，但是你的模型仍然无法工作，寻求正确的方法来获得帮助将使您更快地获得解决方案。
+您可以将您的问题发布到<a href="https://discourse.threejs.org/" target="_blank" rel="noopener">three.js forum</a>，
+	同时，尽可能将你的模型（或者一个简单的、具有相同问题的模型）包含在你能够使用的任何格式中，为其他人提供足够的信息，以便快速重现这个问题——最好是一个能够现场演示的Demo。

+				Three.js使用*matrix*编码3D变换 - 平移（位置），旋转和缩放。 [page:Object3D]的每个实例都有一个[page:Object3D.matrix matrix]，用于存储该对象的位置，旋转和比例。 本页介绍如何更新对象的转换。
+		</p>
+
+		<h2>Convenience properties and *matrixAutoUpdate*(便利属性和 *matrixAutoUpdate*)</h2>
+
+		有两种方法可以更新对象的转换：
+		<ol>
+			<li>
+				修改对象的* position *，* quaternion *和* scale *属性，让three.js重新计算
+				来自这些属性的对象矩阵：
+				<code>
+				object.position.copy(start_position);
+				object.quaternion.copy(quaternion);
+				</code>
+				默认情况下，* matrixAutoUpdate *属性设置为true，并且将自动重新计算矩阵。
+如果对象是静态的，或者您希望在重新计算时手动控制，则可以通过将属性设置为false来获得更好的性能：
+				<code>
+				object.matrixAutoUpdate = false;
+				</code>
+				更改任何属性后，手动更新矩阵：
+				<code>
+				object.updateMatrix();
+				</code>
+			</li>
+			<li>
+				直接修改对象的矩阵。 [page：Matrix4]类有各种修改矩阵的方法：
+				<code>
+				object.matrix.setRotationFromQuaternion(quaternion);
+				object.matrix.setPosition(start_position);
+				object.matrixAutoUpdate = false;
+				</code>
+				请注意，在这种情况下，* matrixAutoUpdate * <em>必须</em>设置为* false *，并且您应该确保<em>不</em>调用* updateMatrix *。 调用* updateMatrix *将破坏对矩阵所做的手动更改，从* position *，* scale *重新计算矩阵，依此类推。
+			</li>
+		</ol>
+
+		<h2>Object and world matrices(对象和世界矩阵)</h2>
+		<p>
+		对象的[page：Object3D.matrix matrix]将对象的转换<em> 相对于 </em>对象的[page：Object3D.parent parent]; 要在<em> 世界 </em>坐标中获取对象的转换，您必须访问该对象的[page：Object3D.matrixWorld]。
+		An object's [page:Object3D.matrix matrix] stores the object's transformation 
+		</p>
+		<p>
+		当父对象或子对象的转换发生更改时，可以通过调用[page：Object3D.updateMatrixWorld updateMatrixWorld]（）来请求更新子对象的[page：Object3D.matrixWorld matrixWorld]。
+		</p>
+
+		<h2>Rotation and Quaternion(旋转和四元数)</h2>
+		<p>
+		Three.js提供了两种表示3D旋转的方式：[page：Euler Euler angles]和[page：Quaternion Quaternions]，以及两者之间的转换方法。 欧拉角受到称为“万向节锁定”的问题，其中某些配置可能失去一定程度的自由度（防止物体绕一个轴旋转）。 因此，对象旋转<em>始终</em>存储在对象的[page：Object3D.quaternion quaternion]中。
+		</p>
+		<p>
+		该库的早期版本包含* useQuaternion *属性，当设置为false时，将导致对象的[page：Object3D.matrix矩阵]从欧拉角计算。 这种做法已被弃用 - 相反，您应该使用[page：Object3D.setRotationFromEuler setRotationFromEuler]方法，该方法将更新四元数。

 				This Bloom Pass is inspired by the bloom pass of the Unreal Engine. It creates a mip map chain of bloom textures and blur them
 				with different radii. Because of the weigted combination of mips, and since larger blurs are done on higher mips, this bloom
 				is better in quality and performance.
