Abstract

We describe experiences during the investigation of parallel methods for faster isosurface generation on SIMD machines. A sequential version of a well known isosurfacing algorithm is algorithmically enhanced for a particular type of SIMD architecture. The SIMD implementation takes full advantage of the data parallel nature of the algorithm and experiments have proven the implementation to be highly scalable. A parallel tool, which can generate 170K polygons / second, gives scientists the means to explore large 3D scalar or vector fields interactively.
