DescriptionOur technique samples candidate positions across all triangles in a scene and then resamples them proportional to direct and indirect illumination at the primary vertex using ReSTIR. We approximate indirectly reflected radiance using DDGI with direct illumination. Our method runs in 20ms (including denoising) at 1080p on an RTX 3090.
