Crest lines are used in computer graphics for a variety of applications because they can convey specific 3D shapes effectively, while they give only little visual representation of a model. In this paper, we present a detection method of crest lines on triangle meshes by the angle of normals of two neighboring triangular facets. Firstly we compute the normal of each triangle and the angle between the normals of the two neighboring triangles is gotten. Secondly, we estimate the threshold according to the angles. Finally, we used the threshold to detect the crest lines on 3D meshes.
