摘要
数字地形模型(DTM)的构建与可视化在很多领域都有着重要的应用,文中基于OpenGL三维图形库及其工作原理,对三维真实感地形生成的基本过程进行详细剖析,采用diamond-square算法,对其过程进行优化处理,编程实现三维地形的模拟,并进行相关的纹理设置构造逼真的三维地形。
The digital terrain model construction and visualization have the important applications.A detailed analysis is made on the process of real 3Dterrain generation based on the OpenGL 3Dgraphics library and working principles.The diamond-square algorithm is used to optimize the process and programming to achieve a 3Dtopography simulation and set the texture to construct a realistic 3Dterrain.
