Abstract
A lighting simulation process for simulating the lighting of a subject at a location in a scene. Scene illumination data is created that specifies the illumination that the scene provides at the location at which the subject is to be simulated from a plurality of spatial directions. Subject illumination data is created that specifies the appearance of the subject when illuminated from a plurality of different spatial directions. The subject is then illuminated as if at the location in the scene by combing the scene illumination data with the subject illumination data.
