ABSTRACT:
The present invention provides an improved system and method for rendering shadows in a computer graphics system. Textures representing the area of influence resulting from a combination of light sources and shadow casters are pre-computed. Scenes are then rendered using the pre-computed textures. A first step entails generating sets of directions and associated pre-computed textures for each light source and shadow caster pair in a simulation frame. Next, a first scene in the simulation is rendered. During this step one or more of the pre-computed textures are used to darken the area of influence or shadow portion of the scene.
