Smooth feature line detection for meshes
摘要
In this paper the authors present a novel semi-automatic line detection technique for meshes. Taking into account the distance and orientation between two vertices on meshes and the curvature information of vertices, they first find an initial line which connects some user-specified vertices on meshes; then parameterize the feature surrounding the line onto a planar domain using a vertex flattening technique; and refine the flattened strip using the 2D snakes approach to make the line smoother and more accurate; lastly they get the line by mapping the refined line back to the original meshes. Experimental results showed that their method can extract the line rapidly and precisely. As an application, they propose a mesh decomposition method based on the detected line.
