Animating radiosity environments through the Multi-Frame Lighting Method

Realistic rendering animation is known to be an expensive processing task w hen physically based global illumination methods are used in order to impro ve illumination details. This paper presents the Multi-Frame Lighting Metho d, an efficient algorithm to compute animations in radiosity environments. The method, based on global Monte Carlo techniques, performs the lighting s imulation of groups of consecutive frames in a single process. All frames c omputed have the same accuracy as if they were computed independently while a significant high speed-lip is achieved. Results show that the method it is an interesting alternative for computing non-interactive radiosity anima tions for moderately complex scenarios. Copyright (C) 2001 John Wiley G Son s, Ltd.
