摘　　要：针对大规模三维场景可视化问题 ,提出了以数据分割、动态调度和多线程并行处理为主要思想的解决方案 ,并重点对多线程并行处理方法进行了研究 ,提出通过合理协调 I/O线程与绘制线程的分工及同步 ,更加充分利用机器的计算资源 ,以获得最佳的绘制效果 .studies the optimizing technologies in visualization of a large scale scene , especially multi threaded collateral method. We propose that technique like partition,dynamic I/o and multi threaded should be used to get a steady render rate .To use multi thread ,the resource and task for every thread should be explicit ,and additional measures should be used to ensure synchronization between them. And also we apply other optimizing methods like MRM、culling and so on. We have experiment on this method in developing a demo system for some water area, and the result is satisfied.
