Abstract

In the medical field, volume rendering provides good quality 3D visualizations but is still not interactive enough for a day-to-day practice. The most efficient sequential algorithm is the Shear-Warp algorithm. It renders up to 10 images per second for a small dataset. The goal of this paper is to present an efficient parallel implementation of the Shear-Warp algorithm for a distributed memory architecture, a cluster of PCs connected with a high speed network.
