GLOBAL ILLUMINATION USING SHARED LIGHTING CONTRIBUTIONS FOR INTERACTIONS IN PATH TRACING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240265620 titled 'GLOBAL ILLUMINATION USING SHARED LIGHTING CONTRIBUTIONS FOR INTERACTIONS IN PATH TRACING
Abstract: The disclosed approaches involve interactions of secondary rays of light transport paths in a virtual environment to share lighting contributions when determining lighting conditions for a light transport path. Interactions may be shared based on similarities in characteristics (e.g., hit locations), defining a region where interactions may share lighting condition data. The region may correspond to a texel of a texture map, and lighting contribution data for interactions may be accumulated to the texel spatially and/or temporally. This data is then used to compute composite lighting contribution data that estimates radiance at an interaction. Approaches are also provided for reprojecting lighting contributions of interactions to pixels to share lighting contribution data from secondary bounces of light transport paths while avoiding potential over-blurring.
- Interactions of secondary rays of light transport paths in a virtual environment are used to share lighting contributions.

Original Abstract Submitted
disclosed approaches provide for interactions of secondary rays of light transport paths in a virtual environment to share lighting contributions when determining lighting conditions for a light transport path. interactions may be shared based on similarities in characteristics (e.g., hit locations), which may define a region in which interactions may share lighting condition data. the region may correspond to a texel of a texture map and lighting contribution data for interactions may be accumulated to the texel spatially and/or temporally, then used to compute composite lighting contribution data that estimates radiance at an interaction. approaches are also provided for reprojecting lighting contributions of interactions to pixels to share lighting contribution data from secondary bounces of light transport paths while avoiding potential over blurring.
