Interactive Volume Visualization on a Heterogeneous Message-Passing Multicomputer

This paper describes VOL2, an interactive general-purpose volume renderer based on ray casting and implemented on Pixel-Planes 5, a distributed-memory, message-passing multicomputer. VOL2 is a pipelined renderer using image-space task parallelism and object-space data partitioning. We describe the parallelization and load balancing techniques used in order to achieve interactive response and near-real-time frame rates. We also present a number of applications for our system and derive some general conclusions about operation of image-order rendering algorithms on message-passing multicomputers. 1 INTRODUCTION AND PREVIOUS WORK Volume rendering is a widely used visualization method. Due to the large number of graphics primitives (voxels) which must be visited during the image generation process, real-time (or even interactive) frame rates are difficult to achieve, even on highestperformanc
