| 摘 要： | 建模方法是三维地质模型及其可视化研究的核心内容。针对连续体终止、错断位移等复杂地质体3D地质建摸的需要，本文对现有的三棱柱数据模型进行了改进，构建了完整的数据结构及其初步的拓扑关系，提出了基于改进三棱柱模型的连续体和不连续体的建摸算法，使其在处理地层尖灭、断层等复杂地质问题时更为灵活、适应面更广。

| Abstract: | The modeling method is the key for study of 3D geological model and visualization. In need of 3D modeling for complicated geologic body such as continuous object termination and continuous object breaking, this paper improves the triangular prism data model, constitutes integral data structure and certain topological relation, and put forward the modeling algorithms for continuous object and discontinuous object based on the improved triangular prism model. This modeling method is propitious to deal with the special geologic modeling problems such as depositional termination and fault. |
