Claim 0:
1. A method comprising:
comparing one or more characteristics of an interaction of a light transport path within a virtual environment with one or more criteria corresponding to a cache, the one or more criteria indicating first radiant power at the interaction is similar in magnitude to second radiant power at each of one or more other interactions within the virtual environment that have one or more samples of the second radiant power stored in the cache;
based at least on the comparing indicating the one or more characteristics satisfy the one or more criteria, determining radiance at the interaction in the light transport path using the one or more samples stored in the cache as at least one sample of the first radiant power for the interaction;
determining radiance of the light transport path using the radiance at the interaction; and
generating a rendered frame using the radiance of the light transport path.
