LIGHT-RESAMPLING WITH SURFACE SIMILARITY TEST

Abstract:

Devices, systems, and techniques to incorporate lighting effects into computer-generated graphics. In at least one embodiment, a graphical frame depicting a virtual scene comprising is rendered by generating a record indicative of one or more lights in the virtual scene, and using the record to render a pixel. A second record, indicative of other lights in the virtual scene, is selected to combine with the first record, based at least in part on similarity between surfaces associated with the respective records. The combined record is used to render a pixel in a second graphical frame.
