Description: Technical Report
Abstract: This report presents a divide-and-conquer approach to developing visualization software for scientific analysis of high resolution, volume datasets on distributed memory parallel computers. Two complementary methods for exploring volume datasets are discussed, isosurface generation and direct volume rendering, and the logic behind the design of parallel implementations of the original sequential algorithms is highlighted. For both algorithms, the data, once distributed, remains in place regardless of the viewer's location, and no interprocessor communication is required during scene generation. Development of the algorithms' communication structure is also discussed, with an introduction to issues surrounding parallel 110 and data distribution for these implementations. Finally, basic parallel performance metrics will be outlined, and test results indicating the performance results of the parallel implementations on an nCUBE 2 will be discussed.
