*Volume rendering* is a powerful, but computationally intensive, computer graphics technique for visualizing volumetric data sets. This paper presents results of investigations into techniques for volume rendering using parallel processing on a shared-memory, multiple-instruction, multiple-data (MIMD) architecture. In particular, two widely used algorithms for volume rendering, *raycasting* and *projection*, have been parallelized on a BBN TC2000, and their performance has been measured and analyzed. Preliminary results indicate that the raycasting approach to volume rendering has some advantages for parallelization on this type of architecture.
