WebHierarchical radiosity (HR) [14] overcomes these problems by decomposing the matrix of interactions into O(n) blocks, for a given accuracy. These blocks correspond to interactions of roughly equal magnitude, and the same computational effort is required for com-puting each block. HR operates by constructing a hierarchical sub- WebWe have developed a radiosity system that computes radiosity solutions for very large polygonal models. The first innovation in this system is that it uses visibility oracles and hierarchical methods to: 1) reduce the number of polygon-polygon interactions considered, and 2) partition the computation into a sequence of subcomputations each requiring a …
