Classification: CPC G | IPC G

Claim 16:
17. A processor comprising:
one or more circuits to render an image using radiance of a light transport path that is determined using radiance at an interaction of the light transport path within a virtual environment, the radiance at the interaction determined based at least on:
comparing one or more characteristics of the interaction with one or more criteria corresponding to a cache, the one or more criteria indicating radiant power at the interaction is similar in magnitude to radiant power at each of one or more other interactions within the virtual environment that have one or more samples of the radiant power stored in the cache; and
based at least on the comparing indicating the one or more characteristics satisfy the one or more criteria, using the one or more samples stored in the cache as at least one sample of the radiant power for the interaction to determine the radiance at the interaction in the light transport path.
