Happy with results for real-time, but still work to do for correctness and stability over high depth complexity. Have to leave off here before SIGGRAPH. Will experiment with 1 screen-space cascade for pixel-perfect contact shadows.

SPWI global illumination in 3D with Radiance Cascades and @garrettkjohnson’s three-mesh-bvh.
Probes are placed in screen-space and trace world-space intervals into a BVH. Resolves offscreen emitters and occluders; memory use tied to screen.
Zero-shot, no noise, and fixed cost. https://t.co/zVVhvTCxWV
