Shaders

• BDTFs (eg. dielectric)
• Choice of shadow types (raytraced/shadow map)
• Adaptive sampling in integrator
• QMC/low-discrepancy random number sampling
• Additional glossy distribution functions eg. GGX, Beckmann
• Solid angle -> filter region calculation for texture lookups
• Texturable brdf properties (eg. roughness)
• Point cloud methods:

• caching illumination, to be read on secondary ray hits rather than shading
• or older-style reading radiance directly from point cloud

• Optimisations:

• Benchmark/check different methods of sampling, eg. batching vs calling shader methods directly
