An implementation of the multigrid algorithm presented here is able to solve the classic radiosity equation in about 50% of the time required by the more commonly-used Gauss-Seidel approach. Although few researchers currently use classic radiosity, we discuss possibilities for the adaption of multigrid methods to more recent radiosity solution techniques.
