description 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.
