TODO:

  • automatically add directional light for sun, remove that
  • check if resource creation modifies state
  • how vulkan binds textures to uniforms and framebuffers?
  • move SSAO init to pex-fx/ssao
  • move debug drawing to a separate file

Context state mapping to Command properties

Possible Context states and equivalent Command properties

If I rename color to clearColor and depth to clearDepth i can get rid of createClearCommand all together

Questions:

  • would it be good idea to replace viewport: [l,r,b,t] with [x,y,w,h]? What do regl and THREE.js do?
  • framebuffer attachments are ugly
