Information-Theory-Based Oracles for Hierarchical Radiosity

In the radiosity method scene meshing has to accurately represent illumination variations avoiding unnecessary refinements that would increase the computational cost. In this paper we present three refinement criteria for hierarchical radiosity which are based on the information content of a ray bet...
