基于Delaunay构网的地层2D，2.5D建模
数值分析 Delaunay三角化 地层 建模
2007/12/12
将地质勘探中的钻孔数据抽象为离散点源信息，设计了离散点的二分拓扑数据结构；在此基础上，提出了用三角形表示地层的2D竖直剖面模型与2.5D叠层TIN模型，并采用Delaunay算法构建模型，同时对断层、尖灭等突变信息的处理也作了初步探讨；最后对一些典型地层进行了重构。该模型具有三角网，便于数据存储、处理与可视化等固有优点，其建模方法也体现了充分利用计算机、适于海量数据的特点。
The lack of interoperability in 2D design– a study in design offices in Brazil
