Grid构建算法研究及OpenGL下三维可视化

a Study of Algorithm for Generation Regular Grid and 3D Visualization in OpenGL Environment

规则格网(Grid)是数字地面模型(DTM)最常用的表示方法,有着广泛的应用。本文介绍了面绘制的栅格网的自动联结过程,同时在OpenGL开放式三维环境下,进行光照渲染等处理,实现了对电磁资料测量数据的可视化处理,并成功地应用于实际的工程项目,取得了很好的效果。

Regular Grid is the commonly used expression method of DTM, and has the widespread use. This paper introduced a progress of automatic coupling of Regular Grid, based on surface planning. At the same time, it realizes the electron magnetic data visualization processing in OpenGL environment by lighting and colouring. It successfully applied in the actual engineering project, and had obtained the good effect.
