| 摘 要： | 体元构造是三维地层建模的核心。针对地质体的层状结构特征，利用平面不规则三角网，构造三棱柱体元；指出：三棱柱体元的分解与剖分是模型切割重构的关键之所在。在此基础上，通过OpenGL技术实现三维模型的可视化。最后，结合东深供水改造工程，进行了三维地层模型构建及可视分析工作。 |

| Abstract: | Volume element structure is the core of modeling of three_dimensional stratum. According to the layer structural features of geological body, the volume element of triangular prism is constructed by plane irregular trigonometric framework. At the same time, the authors point out that the decomposition and division of the volume element of triangular prism is the key problem of modeling and reconstruction. The visual of three_dimensional model can be handled by Open GL technology. The modeling of three dimensional stratum and visual analysis are conducted combining with water supply reconstruction project from Dongjiang to Shenzhen. |
| Keywords: | three_dimensional stratum volume element visual technology water supply reconstruction project from Dongjiang to Shenzhen |
