摘要: 为了清晰地展现模型的内部细节,需要对三维地质模型进行剖切、开挖等分析处理。该文基于空间三角网切割算法TriCut,提出了单个块体的平面剖面生成算法,该算法可实现任意形状的复杂块体的平面剖面的自动、快速、准确的生成。根据该算法实现了地质模型的任意切割分析功能,包括生成剖面图、栅状图等可视化的图件以及基坑开挖、隧道模拟等功能。

关键词: TriCut, 三维地质模型, 剖面, 切割分析

Abstract: In order to exhibit internal details of a model, it needs to process 3D model’s analysis such as cutting, digging and so on. This paper, based on spatial triangle network cutting algorithm——TriCut, brings out a new algorithm to create single block’s planar section. This algorithm can realize automatic, quick and exact creation of complex block’s planar section. And based on this algorithm, arbitrary incision analysis function of geological model is finished which includes creating 3D section chart and bar chart, digging pit, tunnel modeling and so on.

Key words: TriCut, 3D geological model, section plane, incision analysis
