Based on the frame animation data, respective illumination values are computed for the individual polygons of the control mesh to determine the global illumination of the scene. The computation is performed iteratively utilizing the directional light functionally emitted from source polygons to receiver polygons to determine global illumination. The directional light emitter values are further utilized, in combination with material properties, specular illumination contributions to the global illumination of the receiver polygons. | 2008-10-23 |
