Abstract :
Describes a technique for achieving fast volume ray-casting on parallel machines, using a load-balancing scheme and an efficient pipelined approach to compositing. We propose a new model for measuring the amount of work one needs to perform in order to render a given volume, and we use this model to obtain a better load-balancing scheme for distributed memory machines. We also discuss in detail the design trade-offs of our technique. In order to validate our model, we have implemented it on the Intel iPSC/860 and the Intel Paragon, and conducted a detailed performance analysis
