Webing radiosity algorithms (hierarchical radiosity with volume clustering) is used on a detailed model, a solution takes over ten minutes (Figure 19a)1. If, on the other hand, the input geometry is simpliﬁed by cutting the number of triangles by a fac-tor of 100, and the same algorithm is applied to the simpliﬁed model, a solution Web1 de jan. de 2011 · Hierarchical radiosity and Monte Carlo radiosity are branches of radiosity research that focus on complementary problems. The synthesis of both families of radiosity algorithms has however received little attention until now. In this paper, a procedure is presented that bridges the gap.
