摘要
本文所采用的可视化方法思路来自VTK(Visualization Toolkit),基本思想是基于体元的绘制方法,先使用数学插值将空间任意离散的点生成规则的点数据,并对数据点划分成N多个小体元,然后以体元为基本单位进行地质体可视化,体元划分越多,绘制越精确。具体实现是在MFC基础上,配合使用VisualC++提供的AppWizard创建出应用程序框架,再基于该框架进行OpenGL程序开发。其具有精确度高和可扩展能力强等优点。
The visual method of this article is taken from VTK ( Visualization Toolkit) , the basic idea is that the rendering method basing on the cell. First we use mathematics interpolation to produce the regular point basing on the discrete points and divide the points into N little cells to display geological body visualization.With more cells,the result is more precise.The concrete method is with OpenGL programming technique basing on MFC(Microsoft Foundation Class Library) and AppWizard application framework sup-plied by visual C++.It has the characters of novelty, precise and strong extensible ability.
