Parallel Volume Rendering for Unstructured Grid Volume Data on a PC Cluster of Multicore Processor

摘要

A cell-projection parallel volume rendering system for unstructured grid volume data is proposed in this paper. For this system, the modified early ray termination scheme is proposed to prune the cell-projection of invisible cell. In order to alleviate load imbalance due to view-dependency in scan-conversion and the dynamic behavior of early-ray termination, the authors also implement dynamic load balancing mechanism into their system. In addition, we have inspected the effect of multicore processor on this system. We need careful cosideration on the process assignment to achieve best performance.
