摘　　要：提出了一种以似三棱柱体为体元的三维地质构模改进算法,该算法能适用于复杂地质体(如含空洞、矿体、尖灭及断层的地质体)的三维建模,还可用于诸如矿井和巷道等地质特有现象的三维建模,实现了地质体的统一建模。借助于OpenGL三维图形库,可实现地质模型的三维可视化及地质模型的多面剖切,为挖掘3D地质模型信息提供强有力的支持。An improved 3D modeling algorithm based on quasi tri - prism volume elements for geological body is put forward, this algorithm can be applied to the 3D modeling of complicated geological body （such as the geological body including the cavity, ore body, pinching and fault） , also be used in the 3D modeling of the peculiar phenomena of geology such as mine and tunnel etc. , so it can realize the unified modeling of the geological body. With the aid of three - dimensional graphic library Open-GL, the visualization and any section view of geological three - dimension model can be achieved by using this improved algorithm, this offers powerful support for excavating the information of 3D geological model .
