The computational expense of volume rendering motivates the development of parallel implementations on multicomputers. Parallelism achieves higher frame rates, which provide more natural viewing control and enhanced comprehension of 3D structure. Although many parallel implementations exist, we have no framework to compare their relative merits independent of host hardware. The article attempts to establish that framework by enumerating and classifying parallel volume-rendering algorithms suitable for multicomputers with distributed memory and a communication network. It determined the communication costs for classes of parallel algorithms by considering their inherent communication requirements.<>
