Claim 12:
13. A system comprising:
one or more processors; and
one or more memories to store instructions executable by the one or more processors and when executed by the one or more processors cause the one or more processors to at least:
obtain one or more light samples at least in part by ray tracing a set of first rays;
trace a second ray from a point on a surface visible in a first image region to a selected light sample of the one or more light samples, the second ray being more computationally costly than at least one of the set of first rays;
determine at least one visibility parameter indicating an amount of light contributed to the point by the selected light sample along the second ray, the at least one visibility parameter corresponding to the selected light sample and indicating a first amount of light to apply to the first image region; and
determine a second amount of light to apply to a second image region based at least in part on the at least one visibility parameter, the second image region neighboring the first image region at least one of spatially or temporally.
