Abstract
Techniques are disclosed for using a local lighting representation to explicitly model spatial variation of a character in a graphics scene as well as for using error driven criteria to determine whether to evaluate a given light source analytically or in a lighting rig. For near light sources, the error driven criteria may be used to determine when a spherical light source should be evaluated in the lighting rig verses analytically. For large characters, local irradiance models may be used to provide a limited form of spatial variation.
