Adaptive precomputation of glossy interreflections


Precomputed radiance transfer methods compute a global light transport model —the transfer function— to enable real-time rendering of scenes under dynamic distant illumination for arbitrary viewpoints. Usually this transfer function is represented for directions and surface points that are defined a priori. In this paper, we present a precomputed radiance transfer technique, which adaptively chooses directions and surface points during precomputation based on heuristics that are easy to compute. We also present an efficient method for estimating our transfer function model. Both contributions combined enable us to demonstrate real-time renderings with accurate glossy interreflections.
