【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 reasonableness of geological surface modeling and to perfect the function of plane and section 3D linkage editing of 3D geological modeling software, the irregular triangle network model constructed in "3D assistant of geological engineer" modeling software is proposed. A triangulation switching edge algorithm is proposed, and the feasibility of the algorithm is verified by coding in this software. The results show that the triangulation switching edge algorithm can edit the corresponding contour plane and section map and update the topological relation of triangular net automatically while editing 2D and 3D triangulation.
