Abstract
A surface generated from a radiosity simulation is shaded. The surface is divided into a plurality of elements and a brightness value is calculated for each of the elements. An initial surface shading is defined in which the resolution of shading is determined in response to the highest element density of the surface. Element brightness values are processed to generate brightness values for the initial surface shading and values of the initial surface shading are filtered to generate brightness values for an enhanced surface shading. Brightness values of a plurality of elements may be combined to generate a single texel brightness value in the initial surface shading. The filtering step may include steps of increasing the resolution of the initial surface shading and filtering the increased resolution shading. A galcion filtering process may be performed.
