SVO GI

[FacoBackup]

• [ ] Based on first voxel leaf hit, obtain the normal and fire a new ray using the normal's direction
  • [ ] Collect the second hit color and write it to the texture
  • [ ] If nothing is hit during the second bound, then collect the sky color at that ray direction
  • Generate
  • [ ] Configurable ray count
• [ ] Render at quarter resolution
• [ ] Post process like current GI method (downsample -> blur -> upsample -> blur)

Voxel information

• Data buffer
• Voxel stores index on data buffer

Data buffer

• Material ID
  • On hit sample material
• Voxel normal

Debug

• [ ] Voxel visualization move to fragment shader
  • Voxel random color based on position hash
