misc todo & ideas

[i-saint]

• add an option to select objects for shadow caster/receiver independently
• hit mask layer
• object space skinning
  • see "Animation" in http://intro-to-dxr.cwyman.org/presentations/IntroDXR_RaytracingAPI.pdf
• handle drag & dropped scenes from Hierarchy
• export to image functionality
• debug functionality: timestamp
• debug functionality: 'always update acceleration structures' mode
• multiple command lists for deform & building BLAS (for potential parallelization)
  • the performance gain was negligible or even negative. probably it will be better if do it with optimal task granularity in a complex scene. we need to test with real-world assets.
  • https://developer.nvidia.com/dx12-dos-and-donts
• use global root signature instead of local root signature
  • GPU based validation was the source of annoyance
• flip caster mesh faces option
• ID3D12Device::SetStablePowerState()
• handle dynamic Meshes
  • Alembic meshes, etc
• faster BLAS update for baked meshes
  • for Cloth
• use Lights' culling mask
• use Cameras' culling mask
• use MeshRenderer's shadow mode
• use Lights' shadow settings
• set light index to light alpha
• bit mask output option
• use CommandBuffers for precise draw order
  • actually not needed
• (unity) global shader parameter to detect RTHS is used
• normalize light intensity
• debug view for adaptive sampling
• optimal shadow ray offset
  • see "A Fast and Robust Method for Avoiding Self-Intersection" in http://www.realtimerendering.com/raytracinggems/unofficial_RayTracingGems_v1.5.pdf

it would be great if you could pass unity's buffers like: "normal, albedo,..." in the shader "rthsShadowDXR.hlsl"
