摘要 提出了基于动态数据分布的并行 Shear- Warp体绘制算法和新的动态数据分布策略 ,利用空闲的广播通信线路使数据重分布与绘制并行进行 ,提高了通信线路的利用率 ,避免了数据的冗余存储 ,减少了资源浪费 ,并避免了对算法效率的影响 ;改进的任务分配与负载平衡策略 ,避免了节点机负载的不平衡和流水线作业的积压 。 This paper proposes a new parallel shear warp volume rendering algorithm based on dynamic data distribution. As a result of the dynamic data distribution strategy, the algorithm can make use of the idle broadcast communication line to perform data distributing and rendering in parallel. The new algorithm improves utilization of the communication lines, avoids redundant data storage and reduces resource waste. The improved task distribution and load balancing strategy avoid imbalance load on computing nodes and job jam in pipeline, and improve the efficiency of the algorithm.
