• Most radiosity techniques store radiosities in certain sample points, typically the vertices of polyhedral scenes. As diffuse radiosities are view independent they can be used for an interactive 'walk-through'. This paper presents an algorithm for storing radiosities independent of the representation of the object. A distributed rendering system, which uses this shadow-mapping technique is described. The basic thermophysical definitions, needed to derive a sum formula for a form factor calculation of polygons, are explained.
