摘　　要：针对大规模三维地形可视化远远超出了计算机硬件数据处理能力的问题,分析研究了分页动态加载策略以及Ogre实现原理.基于Ogre开发了对大地形的动态加载和实时渲染程序,针对地形页加载出现的卡顿现象,实现了Ogre对TBB多线程技术的支持,地形漫游时程序整体运行流畅.将整套程序移植到了MFC框架下,后续可以方便地在此基础上做二次交互开发.Large-scale 3D terrain visualization is too hard to process for popular computers, and tiaereIore, a paging dylaamic loading strategy and the Orge realization theory were analyzed. The authors developed a dynamic loading arid real-time rendering program for processing large-scale terrain based on Ogre, realized the support of Ogre for multithread technology, so as to overcome the blockage in page loading. The program operates smoothly in terrain roaming. The complete set of program was transplanted into MFC framework for facilitating subsequent secondary in- teractive development.
