地质曲面“三维联动编辑”的一种实现方法

One implementation method of geological surfaces' 3D interaction editing

    摘要
  • 摘要: 为提高地质曲面建模的精确度和合理性，完善三维地质建模软件的平、剖面三维联动编辑功能，针对"地质工程师三维助手"建模软件中构建的不规则三角网模型，提出了三角网交换边算法，并在此软件中编码实现并验证了此算法的可行性。结果显示：三角网交换边算法在编辑二维和三维三角网的同时，能够联动编辑对应的等高线平面图和剖面图，并自动更新三角网的拓扑关系。

     

    Abstract: In order to improve the accuracy and rationality of geological modeling, improving the function of plan and section 3D interaction editing in 3D geological modeling software, an edge exchange algorithm is proposed in this paper, and coded and verified on TIN surface in the software Geologist 3D Assistant (G3DA). The results show:the edge exchange algorithm can edit the 2D TIN, 3D TIN, and the corresponding contour plan and section at the same time, and update topological relationship of the 2D/3D TIN automatically.
