Abstract

Image data is generated from scene data, possibly within a virtual set. The scene data defines surfaces and a plurality of lighting banks. A multi-resolution representation of a radiosity equation is constructed with respect to the scene data. The radiosity equation is solved individually for each of the light banks. A light bank for which a solution is being sought is switched on with the remaining light banks being switched off.
