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 between two patches or elements and the loss of information transfer between them due to the discretisation. The results obtained with our information-theory-based oracles improve on the classic ones based on transported power, kernel smoothness, and smoothness of received radiosity. © Springer-Verlag 2003.
