基于OpenGL的地层模型三维可视化图形显示方法

摘要

Visual graphic display of geological bodies provides the visualization of geometric shapes,correlativities and distribution of geological phenomena for the geologists to accurately carry out scientific analyses. Standard OpenGl functions of 3D graphics are briefly introduced and a stratigraphic model and its colour model are established, displaying and cutting of the stratigraphic model are implemented on microcomputer.%地质实体三维可视化图形显示，可以使地质工作者直观地看到地质现象的几何形态、相互关系和分布，准确地进行科学分析。简要介绍了三维图形标准OpenGL的功能，建立了地层模型及其颜色模型，并在微机上实现了地层模型的显示与剖切。
