Abstract

Methods for rendering an object includes determining diffuse illumination values (430) for object (800) surface points (940), associating a 3D grid including vertices with the object, mapping object surface points to vertices, determining diffuse illumination values for vertices from the diffuse illumination values for object surface points, low pass filtering diffuse illumination values for the vertices to determine illumination compensation values (1265) for the vertices, determining illumination compensation values for the object surface points from the illumination compensation values for the vertices, and determining compensated diffuse illumination values for the object surface points from a weighted combination of the diffuse illumination values and illumination compensation values for the surface points.
