Abstract
Image data is generated for a scene, in which the scene includes object surfaces in three-dimensions. Intersecting or touching surfaces are identified by analyzing the surfaces within a hierarchy of bounding volumes. Thereafter, a multi-resolution representation of a radiosity equation is constructed for the scene, wherein one of the identified surfaces is considered separately for light emission on either side of a previously identified line of contact or intersection.
