Abstract: "Volume rendering is a powerful, but computationally intensive, computer graphics technique for visualizing volumetric datasets. 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."

Abstract: "This paper presents a divide-and-conquer ray-traced volume rendering algorithm and a parallel image compositing method, along with their implementation and performance on the Connection Machine CM-5, and networked workstations. This algoritm distributes both the data and the computations to individual processing units to achieve fast, high- quality rendering of high-resolution data. The volume data, once distributed, is left intact. The processing nodes perform local raytracing of their subvolume concurrently. No communication between processing units is needed during this locally ray-tracing process. A subimage is generated by each processing unit and the final image is obtained by compositing subimages in the proper order, which can be determined a priori. Test results on both the CM-5 and a group of networked workstations demonstrate the practicality of our rendering algorithm and compositing method."

The effects of cyclically obstructing polyhedra are discussed, and methods for their elimination are described, including the use of the Delaunay triangulation. Methods for converting nonconvex meshes into convex meshes are described. A suite of splatting approximations are presented, which along with other more accurate methods discussed, form a hierarchy of rendering methods that tradeoff image accuracy/quality and generation time. Parallel volume rendering algorithms that include visibility ordering for both convex and nonconvex irregular meshes are investigated and results are given for several versions of parallel algorithms. A performance analysis of one of these algorithms on a high performance MIMD 3D graphics workstation is presented."
