Abstract
This paper presents a depth buffer hardware implementation of the multipath algorithm for radiosity. The implementation makes use of bundles of parallel lines implemented with the OpenGL’s depth buffer. The new algorithm is compared with the earlier painter algorithm implementation and we conclude that the proposed technique can result in half a magnitude of speed increase, and can render the indirect illumination in moderately complex scenes in a few seconds
