Animating radiosity environments through the Multi-Frame Lighting Method

Realistic rendering animation is known to be an expensive processing task when physically based global illumination methods are used in order to improve illumination details. This paper presents the Multi-Frame Lighting Method, an efficient algorithm to compute animations in radiosity environments. The method, based on global Monte Carlo techniques, performs the lighting simulation of groups of consecutive frames in a single process. All frames computed have the same accuracy as if they were computed independently while a significant high speed-up is achieved. Results show that the method it is an interesting alternative for computing non-interactive radiosity animations for moderately complex scenarios. Copyright # 2001 John Wiley & Sons, Ltd.
