Titel
Precomputed radiance transfer as a variance reduction technique - a small case study
Abstract
We present a small case study in which we evaluate the potential of the precomputed radiance transfer (PRT) algorithm as a means of variance reduction in path tracing. We describe how to use PRT solutions as correlated functions for both correlated and importance sampling in a straightforward way and study how each approach reduces noise in images rendered with path tracing.
