Construction of Triangular Mesh with Complex Topology in Reverse Engineering
逆向工程中复杂拓扑关系的三角网格构造

Triangulation is an important step in reverse engineering. In this paper, an approach of triangulation for scan lines is proposed. The kernel of the approach is merging the scan lines located in the same layer and marking discontinuous points on the merged scan lines to facilitate triangulation and construction of topology. The approach get over the difficulty in triangulation with crotch and hole character.
