We factor global illumination into direct light at rasterized primary surfaces and two indirect lighting terms, each estimated with one path- traced sample per pixel. Our factorization enables efficient (biased) reconstruction by denoising light without blurring materials. We demonstrate denoising in under 10 ms per 1280 × 720 frame, compare results against the leading offline denoising methods, and include a supplement with source code, video, and data.Computing methodologiesRenderingDenoisingreconstructionrealtime path tracingillumination Denoisingreconstructionrealtime path tracingillumination10.1145/3105762.3105774
