Abstract
An image dataset is processed with a shadow map generated from objects in a virtual scene that can cast shadows and the scene is rendered independent of the shadows. The shadow might be edited separately, and then applied to a post-render image of the scene to form a shadowed image. Light factor values for pixels of the shadow map might be stored as summed-area table values.
