Quan Wang, Pengfei Yang, Yuanyuan Jiang, Ling Huang, Geyi Zhang · 2016
Triangular mesh model built by existing surface reconstruction methods still have issues such as dislocation, serial hole, stitching and multilateral collinear. The model existing above-mentioned defects cannot generate standard STL file for 3D printing. To solve these problems, this paper propose a topology structure repair method for triangular mesh model, which containing four types detailed solutions targeting different topology errors. Moreover, in order to improve the effectiveness and superiority, we design a global error connected region and correlative data structure, which can achieve the aim of rapid detection and repair for different topology errors. The experiment results demonstrate that the method is effective in repairing irrational triangular mesh models.
