摘　　要：为了缓解单机环境下系统资源紧张的问题,在分析单机模式3维数据显示缺点的基础上,首先提出分布环境下的数据处理和调度方案,然后给出了一个通用的逻辑层面的系统模型,最后分析多种数据动态调度策略与优化方案,并给出了客户方和服务方的处理流程。得出并行处理在一定程度上可降低硬件成本,加快运算速度,更好完成3维数据处理任务。In order to alleviate the problem of systematic resource shortage which happened under the unit environment, we firstly put forward the data processing and adjusting scheme under the environment of distributing on the base of analyzing shortcomings of 3D data showing in the mode of single unit. And then we provide the general systematic models of a logic aspect. Finally we analyzed the dynamic dispatcher＇ s tactics of multi-data and optimized scheme, and put forward the treatment procedure that provide both in customer＇ s side and serve side. Our conclusion is that the parallel processing can reduce the hardware cost to a certain extent, can accelerate the speed of operation and is much easier to fulfill the 3D data processing task.
