Abstract
A method for rendering a shadow in a 3 D scene includes generating a penumbra map using a z-buffer and generating an occluder map using the z-buffer. The penumbra map and the occluder map are projected into a 3 D scene to render at least one shadow having a penumbra region and an umbra region.
