Abstract:
A method, system and computer program product for managing secondary rays during ray-tracing are presented. A non-visible unidirectional ray tracing object logically surrounds a user-selected virtual object in a computer generated illustration. This unidirectional ray tracing object prevents secondary tracing rays from emanating from the user-selected virtual object during ray tracing.
