摘要
三维地质体可视化是地质研究和工程勘查勘探领域直观表达地层钻探数据必不可少的手段。在三维地质体可视化中为了同时表现地质体的外在特征和内在特征,一般应用基于体元的的建模方法。首先讨论基于三棱柱体体元的建模方法以及基于该建模方法的模型的剖分算法,然后利用该建模方法和模型的剖分算法实现了地质体的显示和虚拟钻探。
Visualization of 3D geological-entities is the necessary way to explain directly drill data in the field of geological study and engineering survey. In order to show the exterior feature and inner feature of geological-entities, usually the model with entity element is built. Firstly, the modeling method based on triangular-prism is discussed, and the incision algorithm of the model is analyzed. Then, the visualization of geological-entities and the virtual drilling are realized by the modeling method and the cutting algorithm.
