GP Direct Planning

[Ipotrick]

• VSMS:
  • improved many lights vs mesh instances culling
  • dynamic object invalidation for point lights and spot lights
  • (not for GP Direct) Quad tree for point and spot light page tables instead of mipchain
• per pixel traced indirect diffuse
  • trace diffuse ray per pixel
  • use nvidias recurrent blurr to denoise
  • use spherical harmomics to denoise
  • denoise in half res, upscale to full res
  • pgi for ray hit indirect lighting
  • vsms for direct light shadows
• bloom?
• fog?
• lod transition improvements
• editor
  • gizmo rendering
  • dragging, rotating and scaling objects
  • writing out modified gltfs
• clouds (probably cope though there is no way I have the time to do this)
• IES light profiles
