摘　　要：针对大规模地形可视化的需求,设计并实现了基于WPF的大规模地形可视化系统。阐述了虚拟地球、瓦片金字塔结构、数字高程模型的基本原理及在系统中的应用,设计了基于游戏循环的可视化框架,实现了自由摄像机、瓦片模型调度、瓦片模型生成等关键功能。实验表明,该系统能够实时、准确地实现大规模地形的可视化,具有较高的应用价值。In order to meet the needs of the independent development of large scale terrain visualization, this paper designed and implemented a large scale terrain visualization system based on WPF. This paper mainly introduced the applications of the basic principles of virtual world, tile pyramid structure, digital elevation model, and designed a visualization framework based on game loop. The key functions of the system, such as free camera, tile model scheduling and tile model generation, were also described. Experiment's result shows that the system can realize the visualization of large scale terrain in real time and is valuable to be applied.
