地下水数值模型三维可视化研究

Study on 3-D visualization of groundwater simulated model

探讨了利用OpenGL技术实现含水层三维可视化的原理和方法 ,基于地下水数值模型的有限元三角网格和含水层顶底板信息 ,构建含水层三维实体模型 ,并将地下水数值模型计算结果通过三维表面动画的形式进行动态显示。本项研究为全方位、多视角地展示地下水系统进行了有益的尝试 。

This paper describes how 3 D visualization is achieved through OpenGL techniques.A three dimensional model of the aquifer is created from the Finite Element Method(FEM) grid and the top and bottom aquifer depths information,and groundwater table dynamics is displayed by 3 D surface movies.This study can serve as an example of how the use of 3 D visualization techniques can benefit to decision maker to understand groundwater aquifer.
