曲面网格数据的边缘提取与显示

Detection of Edge of Surface Mesh Data

摘要: 曲面网格数据是有限元计算与实际测量中经常得到的一类重要的离散数据,由于其采样不规则,采样点分布在曲面上,因而已有的图像分析方法不再适用.文中讨论了该类数据的特征分析方法,给出了曲面网格数据中特征区域边缘的自动提取与显示方法.

Abstract: Surface mesh data is a kind of important discrete data obtained in finite element computation and measurement.In the paper,an algorithm is developed for detecting and displaying feature edge from the surface mesh data.
