Simultaneous Progressive Refinement in Dynamic Environments
Jens-Uwe Hahn · OpenGrey (Institut de l'Information Scientifique et Technique) · 1998
This paper presents a new method for efficient radiosity calculation in dynamic environments. The method is intended for animation sequences in which the motion and mutation of the objects is known in advance. The algorithm is based on Wallace's progressive refinement algorithm. Progressive refinement iterations are performed simultaneously for all frames of the animation. Being precise, we give a proof of the convergence of our algorithm to the correct solution. Using our technique, a smooth non flickering illumination is guaranteed during the animation sequence. (orig.)
