    • Lambertian
    • Cook-Torrance, Frostbite:
      • D component: Beckmann, Ward-Duer, Blinn-Phong, Trowbridge-Reitz/GGX/GTR2, Berry/GTR1

  • Color spaces
    • All separate colors from material files are expressed in sRGB color space.
    • All separate colors from color pickers (i.e. ImGui) are expressed in sRGB color space.
    • All separate textures (incl. fonts) are expressed in linear or sRGB color space.
    • All internally stored separate colors are expressed in linear color space (for both C++ and HLSL). Exceptions: All internally stored separate colors of ImGui are expressed in sRGB color space. All internally stored separate colors of the voxelization are expressed in LogLuv color space.
    • All color calculations (inc. filtering and blending) are performed in linear color space (for both C++ and HLSL).
    • Final outputted colors are expressed in a custom gamma encoded color space (i.e. brightness adjustment).

  • Box
  • Tangent (generic tangent space)
  • Object
  • World
  • Camera (>0)
  • Light (>0)
  • Projection
  • NDC (NDC z = non-linear depth)
  • Shading (generic space; e.g., World, Object, Camera, Light, ...)
  • View (generic space; e.g., Object, Camera, Light, ...)

Texture
