摘要
本文利用OpenGL开放图形库的 2 0 0多个函数 ,在前人对三维可视化研究的基础上 ,基于实际生产中的需求 ,提出一种可行的“二次简化法” ,实践证明 ,这种处理方法能够使生产出的三维地形图在兼顾高度逼真的同时 ,能够实际地处理空间分析操作运算 ,满足了生产中的需要。
In this article, we use two hundred functions of OpenGL and put forward a feasible method named 'the bis predigestion ' which is based on predecessor's research and is according to the actual needs in the production, what can be identified in practice is that this method can not only produce the most realistic 3d terrain maps, but also can operate the 3d analysis. It can meet our needs in the production.
