quakespasm

this input node cannibalises quakespasm to read quake input geometry and textures. the data is sent to vulkan ray tracing kernels. you can try vkdt examples/quake.cfg to test it. requires a bluenoise input texture, see below. also it assumes that you have the original game data installed in /usr/share/games/quake/. this module is optional, you need to have compiled with VKDT_USE_QUAKE=1, see config.mk.defaults.

connectors

  • output the rendered frame. this is not a source because it doesn't require cpu copy (rendered on gpu directly).
  • blue blue noise input textures. see this github issue for an example file.
  • aov the arbitrary output variables channel. currently writes diffuse albedo.

parameters

  • cam custom camera parameters passed as uniforms. these are usually ignored, but you can still grab to play the game.
  • spp the number of samples per pixel. lower this to gain speed.
