摘　　要：针对具有高性价比、优兼容性、灵活扩展性的基于PC的并行渲染系统的特点,设计并实现了一个带负载平衡的PC集群sort-first并行渲染系统,并进行了测试,证明了其负载平衡策略对于渲染任务分布不均的实时渲染要求的有效性。文中详细介绍了该系统的结构和实现以及所采用的负载平衡策略,同时介绍了该系统的两个关键技术:归属判断和网络同步。对于归属判断技术给出了具体实现步骤、试验验证数据和结论。对网络同步,介绍了该系统网络通讯和结点同步的具体实现方法。最后给出了系统的测试数据、效果图、以及实验结论。A sort - first parallel rendering system based on PC clusters with load - balance strategy is designed and realized according to the features of the PC based parallel rendering system which is advanced in high performance price ratio, good compatibility and excellent flexibility. Its validity for unbalanced real - time rendering task is proved through test. The paper introduces its structure, realization and load - balance strategy in detail and also presents its two key technologies： belong- determining and network synchronization. As for the former, its particular realizing steps, test data and conclusion are presented. For the latter, the particular realizing steps of its network communication and nodes synchronization are introduced. And the test results, effective pictures and test conclusions are given at the end.
