摘　　要：通过介绍三维地形场景的建模和实验实现方法,在分析国内外常用的地形动态简化技术优缺点的基础上提出了一种多分辨地形模型生成的算法,解决了浏览时对原始地形几何数据和纹理数据的进行实时交互显示的问题。The method and realization process of the three - dimensional terrain visualization is described in this article. An improved algorithm of generating multi - resolution terrain model is proposed based on the analyzing the disadvantage of the algorithms popularly used by the domestic and foreign scholar. The algorithm can meet the demand of the real time display of the original terrain geometry data and texture data during the process of real time alternating browse.
