Abstract
Rendering methods include receiving a 3D object including adjacent first and second objects, determining surface illumination for points on the first and second objects, associating first and second 3D grids with the first and second objects, mapping points of the first and second objects to the first and second 3D grids, determining surface illumination for vertices in the first and second 3D grids in response to the surface illumination for the first and second objects, performing a low pass filter on the surface illumination for vertices in the first and second 3D grids, determining first and second illumination compensation for points on the first and second objects, determining illumination compensation for vertices in the first and second 3D grids in response to the first and second illumination compensation for the first and second objects, combining the filtered surface illumination and illumination compensation for vertices in the first and second objects.
