A method is described which models the interaction of light between diffusely reflecting surfaces. Current reflection used in computer graphics do not account for object-to-object diffuse surfaces, and thus incorrectly compute global illumination effects. The new procedure, based on methods thermal engineering, includes effects sources finite area, as well “color-bleeding” are caused by reflections. simple environment to illustrate these simulated presented with photographs a physical model. procedure applicable environments composed ideal reflectors can direct from variety sources. resultant surface intensities independent observer position, be preprocessed dynamic sequences.
