基于OpenGL的地下水位动态模拟

该文在介绍虚拟现实的基础上 ,讨论了地下水抽取过程中水位的动态变化 ,并以泰斯井为例 ,研究了抽取地下水过程中 ,降落漏斗的产生及水位降落幅度的变化情况。基于OpenGL技术编制了程序 ,可任意旋转 ,平移 ,缩放地下水水位降落漏斗图 ,并运用光照 ,贴纹理及融合等技术增强立体感 ,使其可视化程度较高 ,在程序运行中可控制抽水或停止抽水等操作。

DYNAMIC MODELING OF GROUNDWATER BASED ON OpenGL TECHNOLOGY

Dynamic change of groundwater table during pumping was discussed on the basis of the introduction of virtual reality,and the cone of depression of groundwater and the dropping down rate wetre studied using Theis well as an example.The program was programmed based on OpenGL technique.Three-dimensional contour map of groundwater table can be rotated,moved at any angle and zoomed in and out,and the three-dimensional effect and visualization were strenthened by light,texture mapping and blend technology.Operation such as pumping can be controlled by the program.
