Abstract
A method for creating artistic effects for volumetric illumination in a scene is provided. Data representing a scene is received. User input is received, which specifies a target appearance of the scene, including illumination effects that are at least in part non-physically-based. Photon beams representing volumetric illumination in the scene are generated; this step may incorporate user input-based modifications of the photon beams. Shading associated with the photon beams is computed; this step may also incorporate user input-based modifications. Any modifications in the generating or computing steps are derived from the specified target appearance of the scene. Finally, the photon beams are rendered.
