摘要
基于似三棱柱模型和人工插入虚拟钻孔的方式提出采用虚拟钻孔链控制复杂地质体的新思路,成功设计了一种能够识别褶皱、透镜体、尖灭体、断层和高精度控制边界的推理算法。提出了TIN加密新技术——窗口加密法,发现Delaunay三角形存在"隔离带"现象而实现Delaunay三角网局部重构技术——移动窗口ROI,设计并实现了三种加速算法方案。最后利用C#+Open Inventor实现真三维可视化和地质体高效率切割、挖掘等。
This paper proposed a new method of dummy borehole chain to control the complicated geo-body based on the similar tri-prism model. Designed a smart arithmetic which could self-identify fold, lens body, sharpen body, fault etc. Window densification was an new technology for TIN densification. Realized the Delaunay triangle network＇ s part-reconstruction-technology based on the discovering of Delaunay＇ s new character isolation belt. In order to accelerate arithmetic, proposed three efficient solutions, Finally the complicated geo-hody was 3D-visualized by C# ＋ Open Inventor, which could operate well with geo-body cutting, digging, probe and layer uncovering.
