Abstract
A method for use in computer graphics includes establishing a surface that is represented by at least one polygon that includes a plurality of vertices, establishing one or more light sources that are configured to illuminate the surface, and computing an aggregate light source position for each vertex of the polygon, wherein the computation for each vertex includes averaging directions from the vertex to the one or more light sources. A storage medium stores a computer program, and an apparatus includes a display and a processor based system.
