Title: Method and apparatus for rendering a three-dimensional scene having shadowing

Abstract: A method and apparatus for rendering shadows on a three-dimensional scene is accomplished by generating a light source texture map of the given three-dimensional scene. The light source texture map is generated based on a viewing perspective being proximal to a light source projection. Once the light source texture map has been generated, an object element of the three-dimensional scene is rendered based on the light source texture map and image information. The image information includes vertex components corresponding to object elements of the three-dimensional scene.
