A given computer graphics scene may be rendered as a set of triangles. A set of photons may be distributed over the scene, and a number of steps may be performed for each triangle. For each triangle, a list of photons may be constructed. For that triangle, a set of control points may be identified for purposes of determining global illumination. For each control point, a specific illumination estimate may be computed. A kd-tree of the control points of the triangle may be built. An illumination estimate may then be drive for the triangle.

Diffuse photon map decomposition for parallelization of global illumination algorithm

An apparatus and method for soft shadow calculations, the method including dividing an area light source into a patch of points, obtaining a packet of points on a surface that is subject to illumination by the patch of points, determining a form-factor value for each of the points in the packet of points; and simultaneously performing adaptive soft shadow calculations for each of the points in the packet based on the point in the packet having the greatest form-factor.
