Hey!

Before i start developing my own technique i'd like to ask you if you know any existing methods for determining "sharp" edges on 3d mesh. For example if i have a simple 3d cube model the result of this method would be a list of 12 edges. In this simple example i could just compare angle between triangle normals. But i'd like to extend this to big meshes (a lot of triangles and a bit noisy data) and i'd like to "estimate" where sharp edges are. Any suggestions?
