Abstract
CellFast is an interactive system for unstructured volume visualization. Our CellFast system uses optimizations of OpenGL triangle fans, customized quicksort, memory organization for cache efficiency, display lists, tetrahedral culling, and multithreading. The optimizations improve the performance of an approach similar to Shirley and Tuchman’s projected tetrahedra rendering to provide 1 frame/second for 240,122 tetrahedral cells, 3 frames/second for 70,125 tetrahedral cells, and 15 frames/second for 12,936 tetrahedral cells. CellFast also performs fully automated classification to assist rendering. Demonstration of fluid flow, medical simulation, and medical imaging datasets are provided. CellFast provides for very high resolutions (up to 3840x1024), at frame rates that are orders of magnitude higher in performance compared to those in the literature. The CellFast system combines an interactive renderer and automatic classification to make unstructured volume rendering more useful.
