摘要
地质三维可视化是正确认识地质构造的重要手段,能为矿藏及各种地质现象描述提供科学的依据.本文在AutoCAD平台下,以钻孔信息、剖面图和空间离散点为基础数据,采用顾及台阶属性的Delaunay三角网凸包算法建立界面模型,通过面域拉伸和实体布尔运算或固化成体方法生成三维实体模型。达到了地质三维可视化的目的,并成功地将方法应用于实际的工程项目,取得了很好的效果.
3D visualization of geology is an important means to learn the geo-body structure with useful and scientific proof for descriptions of mines and all kindsof geological phenomena.By using drill hole information,section chartand discrete space pointas fundamental data,the authordesigned a general process of 3D geological modeling based on AutoCAD.The modeling method firstly established facemodel by using a consideringbench attributeDelau-nayTIN convex hull algorithm,then sets up themining solid model by strengthening region and using solid Boolean operation or Curing adult.the goal of the geology 3D visualization is obtained.The algorithm is applied successfully to project-item with a satisfying effect.
