This algorithm used a Heuristic partitioning method which distributes both the data and computations to processing units to achieved fast, high quality rendering. The processing nodes perform local Ray Casting of their subvolume simultaneously. No communication between processing units is needed during this local Ray Casting process. A subimages is gen
