This paper presents a depth buffer implementation of the global line multipath algorithm for radiosity. The implementation makes use of bundles of parallel lines implemented with OpenGL’s depth buffer. For each projection direction the new algorithm uses several pair of depth buffers and exploits coherence between them in order to improve the efficiency. Each depth stores the patch IDs that are projected onto them and a pair of depth buffers with opposite normals are used in order to exchange the energy between patches.
