摘　　要：三维空间建模和可视化技术成为GIS研究的热点之一。可视化技术是当今表达和分析复杂数据的有力工具,将可视化技术引入到DEM和三维地质模型,可以实现三维地形和地质体的生成与仿真。简要介绍了OpenGL三维图形工具包及其与高级语言结合编程方法,探讨了基于多轮廓线的地质三维体的建模方法,以VC++6.0高级程序设计语言为开发平台,结合OpenGL图形库,开发了地质三维体的建模实验系统。D spatial modeling and Visualization technology is one of the hotspots in GIS field. Visualization is a powerful tool of expressing and analyzing complicate data. Its being used in DEM and 3D geo-model, 3D terrain and geologic model will be implemented. In this paper, the knowledge of OpenGL and its programming method embedding in VC++ are introduced simply. 3D geological body modeling method by using multiple contours is discussed. A prototype system is developed under VC++ 6.0 environment combining with OpenGL graphic library.
