Parallel processing for view-dependent polygonal virtual environments Conference Paper uri icon


  • This paper presents a parallel algorithm for preprocessing as well as real-time navigation of view-dependent virtual environments on shared memory multiprocessors. The algorithm proceeds by hierarchical spatial subdivision of the input dataset by an octree. The parallel algorithm is robust and does not generate any artifacts such as degenerate triangles and mesh foldovers. The algorithm performance scales linearly with increase in the number of processors as well as increase in the input dataset complexity. The resulting visualization performance is fast enough to enable interleaved acquisition and modification with interactive visualization.
