Suslik’s Shadertoy (Nov 2024) — a uv-space implementation of RC. Multi-bounce lighting, BRDF integration.
Operates in texture coordinate space of surfaces rather than screen-space or world-space grids. Merging is temporal due to Shadertoy limitations, causing some light lag and flickering — a proper implementation could likely avoid this.
Notable as a proof-of-concept from the original RC author.
