开发了南水北调中线工程三维仿真系统,将整个中线工程及周边地形地貌在计算机上进行了虚拟再现。应用地形自动建模软件TerraVista和地物建模软件Creator,完成了大范围地形地物数据的建模。采用两级地形三级纹理分块动态载入的方法解决大地形调度问题,同时实现了二维导航漫游、信息查询、渠道水流模拟等方面的功能,为南水北调中线工程的研究提供了三维可视化辅助平台。

A 3-D simulation system of the middle route of South-To-North Water transfer project is developed. This system displayed all terrain and buildings in this area. Terra Vista software and Creator software are used to modeling the terrain and buildings. In order to solve the problems aroused by huge data of terrain model, this system dynamically imports terrain models with two kind of precision and three kind of texture. 2-D navigation, information query, channel flow simulation are realized in this system.
