READ FIRST

Major rendering engine update, expect lots of bugs, DO NOT USE for important games. It has had very limited testing and isn't ready yet.

Source-code if you want to build on other systems is available here, process to build is:

git clone https://github.com/meag/ezquake-source new-renderer
cd new-renderer
git checkout meag/renderer

make clean && CLASSIC_OPENGL_ONLY=1 make -j3
make clean && MODERN_OPENGL_ONLY=1 make -j3

Official changelog and individual 3.5 version changelogs moved to here

Lots of changes to classic in this version - started adding GLSL rendering to classic renderer for instance, it also uses texture arrays for lightmaps. Might have more issues on particular cards or configs than usual.

Changes/fixes in latest release

  • ciscon: r_drawflat bugged on modern
  • /vid_framebuffer 1, /vid_framebuffer_scale 0 & /vid_framebuffer_width 0 produces rendering bugs (potential wallhack-like effect)
  • during vid_restart the buffers can be recreated in a different order which causes problems & potential crash

Todo list for next build

  • ciscon: classic rendering bugged (multi-renderer build only)
  • sae: particles can disappear (was when /r_particles_count limit set > 2048, and then > 2048 particles - two explosions with /r_explosiontype 0 + a rocket trail)
  • turning off all /r_smooth* cvars disables hud rendering
  • missing tracker images causes crash on map load
  • changing /gl_modulate updates all lightmaps immediately (old bug)
  • programs should compile ahead of being used, otherwise stuttery performance the first time a program is used in a scene
  • /gl_program_world and lightmaps in texture array is broken (need to make gl_program_world dictate if texture arrays are used, require vid_restart?)
  • removed functionality: velocity3d
  • .md3 models could cause application crash (incorrectly measuring size prior to populating vbo)
  • .md3 viewmodels should have depth buffer hack
  • .md3 models have more flexible .skin support
  • .md3 models with multiple surfaces/textures supported
  • .md3 models don't set modelhint (itemsclock, gamesummary etc broken.. also in 3.1)
  • .md3 model corruption when drawing in modern
  • .md3 model lerping when using VBOs
  • .md3 models are lit as normal
  • .md3 models support /gl_outline
  • .md3 model rendering/lerping in glsl (classic)
  • powerup shell texture is incorrect with /gl_program_aliasmodels 0 in classic
  • /vid_framebuffer & /vid_gamma_correction is double-applying the gamma correction

Todo list (4.0-alpha)

  • .md3/.mdl: add special cases for ng/sng to not lerp back to the frame 0 when firing stops
  • .md3 vertex/colored lighting etc as normal
  • .md3 shader support (keep very basic for now, maybe just blending modes)
  • stop switching programs when drawing different hud elements (especially circles/lines)
  • stop switching back to immediate mode at end of each program call in classic
  • complete classic .glsl rendering path, allow -noimmediate
  • OpenGL 3.2 support (update v120 shaders, ask for core on OSX)
  • bloom functionality in glsl
  • fix proportional font loading for Windows (convert everything to SDL_ttf?)
  • bgnr: fov distortion on vid_restart
  • bgnr: gamma doesn't work, reports "gamma size broken, gamma wont work" (likely to be linux specific)
  • bps: "bug on alpha15 where it glows on the ground on couple of places, like the glow from a quad, currently only on ztndm3" - have downloaded the .mvd and seen demo showing example, happened once on watching demo bug cannot reliably replicate - could have been the GL_BindTextures() bug?
  • dev: screen flickering. (... cannot replicate)
    • initially thought to be only on linux, but seems it happens on windows too after long uptime.
    • (dev reports that mur has same issue)
    • (we now think this is a hud-rendering issue but haven't got to the bottom of it)
  • dev: crash when issuing /vid_restart while fast-forwarding a demo. Error message looks like it might be freeing() memory twice. (command was gl_externalTextures_world 1; gl_max_size 32768; gl_texturemode GL_LINEAR_MIPMAP_LINEAR; gl_loadlitfiles 1; gl_outline 1; vid_restart)
  • lordlame: complaints about performance on radeon 6990 (reports alpha3 runs better)
  • core profile rendering broken on AMD (narrowed it down to draw_world)

4.0 complete

  • vertex/colored lighting in .glsl
  • complete reading user interface from json
  • complete new threading model for server browser

4.1

  • multiple huds per config
  • old-hud should be subset of new-hud rendering
  • customisable scoreboards
  • customise the location of multiview windows
  • look again at gpu-culling of scene, pre-building list of surfaces per vis-area
  • look again at deferred shading

Fixed in 3.5-menus

  • dirtbox: rendering of server browser's server popup window was broken (was connected to server and running server browser and having server-browser window open)
    • full console was drawn in background then painted over before server-browser
    • spaces were still drawn when drawing red text, rather than skipped as normal
    • dialog boxes were rendered as individual blocks rather than repeating tiles (very old issue)
  • meag: crosshairimage is set to an image that is not available, will not load (memory in pool not allocated)
  • meag: proportional font loading is broken (uses new spacing for spaces but still uses fixed-width font)
  • meag: server browser threading model significantly changed
  • meag: user interface functionality significantly changed

Old bugs

  • timon: coronas of rockets in water are visible when out of the water
  • meag: cheap shadows are affected by rotation of item (most noticeable on gibs)

Bugs reported, not being actioned

  • raket: http://upload.foppa.dk/files/ez35love.mkv, rendering to one x server and capturing from another on nvidia. Works on 3.1, 3.5-classic crashes immediately, 3.5-glsl gives the video attached. also breaks cs:go. no bug if ffmpeg capturing setup isn't enabled, raket suspects bug in linux nvidia drivers
  • raket: requested change: detect compositor on x-windows

Hopefully fixed (waiting for feedback)

  • bgnr: text font appears as solid colour (reports that running without config works fine, has supplied config - was .wad font only)
  • bps: crash on last seconds of dm2 (particle-expiring issue fixed in alpha6)
  • dimman: crash when running timedemo demo1 (...cannot replicate, believe might be same as bps)
  • ciscon: on mesa, /vid_gl_core_profile to get > 3.0 on intel card supporting 4.5 no longer works
  • dirtbox: related out of memory error when trying to connect to server (can't get this to happen, but fixed some memory leaks and memory usage should now be much lower)
  • lordlame: vid_renderer 0 > 1 > 0 loses performance increase (performance stays at '1' levels) - AMD system
  • up2: incorrect luma textures used on start.bsp (fullbright player skins layers used instead of brush model luma textures) (... could not replicate but alpha16 fixed bug in GL_BindTextures() call)

Struggling to replicate

  • blah/ciscon: increased memory usage over time (... cannot replicate)
  • nigve: 'q' in tracker isn't blue anymore (can't replicate)
