Discontinuity meshing has greatly enhanced the visual and numerical accuracy of radiosity solutions. However, its computational expense means that it cannot be used in dynamic interactive environments with current hardware. Techniques are proposed which allow the discontinuity information to be reused as the environment changes. These techniques complement existing dynamic radiosity methods which update the global solution for dynamic environments, while preserving the visual accuracy obtained from discontinuity meshing. The resulting system will allow full interaction with the environment, and still provide an accurate solution.
