I wrote a giant list on what I want to implement into this framework to make it full. I’m pretty sure I’ll be done in about 150-200 hours, which I have about 40 days to make before the end of this thing. That is 3.75 - 5 hours of coding in a day. Anyway, here’s the list:

TODO FEATURES:

• lighting
  • gpu scene data uniform buffer
  • ambient light
  • directional light
  • point lights
  • tangent space normal mapping
  • tangent generation in gltf loading
  • dynamic light count
  • proper api for handling lights
• shadow mapping
  • depth-only pipeline
  • shadow map image
  • light space matrix
  • shadow pass
  • shadow sampling in the main fragment shader
  • shadow bias
  • PCF filtering
• material system
  • material struct (albedo map, normal map, roughness map, emissive map, scalar tint and roughness and metallic factors)
  • material descriptor layout
  • default fallback textures
  • gltf material loading
  • draw_mesh api update
  • emissive support in the shader
  • creating and destroying materials for user-made materials
• mipmaps and proper sample management
  • mipmap generation on upload
  • mip count calculation
  • sampler cache (so samplers are never duplicated)
• instanced rendering
  • per-instance storage buffer
  • draw_mesh_instanced api
  • write the shader for it (gl_InstanceIndex)
  • move to indirect drawing so the instance count can eventually come from gpu-side data
• skybox
  • cubemap loading
  • skybox pipeline
  • skybox shader
  • set_skybox api
• frustrum culling
  • bounding sphere per mesh (compute in loading by finding the disctance from the centroid across all vectires)
  • frustrum plane extraction (gribb-hartmann)
  • cull loop
  • stats readout
• post processing stack
  • fullscreen traingle pipeline
  • HDR tonemapping
  • guassian blur api
  • box blur api
  • bloom
  • vignette
• 2D rendering
  • quad mesh
  • 2D pipeline
  • surface class
  • default surface
  • draw_surface
  • draw_rect
  • font atlas rendering
• MSAA
  • multisample draw image
  • resolve attachment
  • configurable sample count
