Abstract :
Discusses our efforts to improve the performance of the high-accuracy (HIAC) volume rendering system, based on cell projection, which is used to display unstructured, scientific data sets for analysis. The parallelization of HIAC, using Pthreads and MPI API´s, resulted in significant speedup, but interactive frame rates are not yet attainable for very large data sets.
