ABSTRACT:
A method for rendering a shadow cast from an object illuminated by at least one light source onto at least another object on a graphical computer display. The preferred embodiment enables the rendering of accurate and realistic shadows in real-time, consequently providing a realistic view of three-dimensional objects in two dimensions. The shadow can also provide more visual clues than are otherwise available from ambient light sources. In this way, more visual information is provided to an observer.
