SDF
June 14th, 2009
The Shape-Diameter Function (SDF) is a scalar function defined on the mesh surface. It expresses a measure of the diameter of the object’s volume in the neighborhood of each point on the surface. Using the SDF we have been able to segment 3D models, find skeletons for deformations and other applications, and perform part-retrieval (see bibliography).
