Volumetric Radiance Cascades (failed)

An attempt at extending radiance cascades from 2D to 3D voxel scenes. I didn't get it to converge into usable GI, but it taught me most of what I now know about probe-based lighting.

What I built

  • Probe hierarchy over a voxel scene with progressively coarser angular / finer spatial resolution.
  • Cascade merging was where it broke down.
