Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. One or more non-transitory computer readable media containing program instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
identifying a subset of pixels of an image to be ray-traced based on variable rate shading (VRS) screenspace image data;
setting, based on the VRS screenspace image data, one or more material properties of at least one object corresponding to the subset of pixels;
determining, based on the VRS screenspace image data, a surviving coverage of the at least one object in a screenspace associated with the subset of pixels; and
performing ray-tracing for the subset of pixels to generate a ray-traced image,
wherein to perform the ray-tracing, the instructions cause the one or more processors to perform a ray casting process based on the set one or more material properties by modulating a number of ray bounces corresponding to the set one or more material properties based on the surviving coverage defined by the VRS screenspace image data.
