Abstract: In this presentation, approaches for achieving moderately high performance (on a single commodity processor) for a very popular volume visualization technique will be presented. The approaches utilize Single Instruction Multiple Data (SIMD) Within A Register (SWAR) capabilities (i.e., streaming media extensions) of recent-generation x86 CPUs. The approaches enable multiple data items to be processed simultaneously without a sacrifice in final rendering quality. Speedups of approximately three to four times have been achieved for large volume datasets. This work is the culmination of several years' work by Dr. Newman and his students at UAH's Computer Science Department.

Biographical Sketch: Dr. Newman is an Associate Professor with UAH's Department of Computer Science.
