2012-Feature detection of triangular meshes via neighbor supporting Wang, X.C., Cao, J.J., Liu, X.P., Li, B.J., Shi, X.Q., Sun, Y.Z. Feature detection on triangular meshes via neighbor supporting. Journal of Zhejiang University-SCIENCE C, 2012, 13(6):440-451. Motivation In the process of model analysis, understanding, and editing, feature detection usually plays an important and preliminary role in a variety of applications, such as feature-preserving mesh denoising, simplification, segmentation, and hole-filling. A crest point has maximum curvature in its corresponding direction and a crest line naturally follows the direction of the minimum curvature of its composing crest point. That is, the feature vertices lie on the principal curvature line. In fact, if v is a feature vertex, there will be more feature vertices that can be located in the principal direction or the opposite principal direction corres
