Size functions are introduced for the first time to discriminate among 3D objects, through the proposal of an innovative method to construct size graphs independently of the underlying triangulation. We demonstrate the potential of our approach in a series of comparative experiments with respect to existing techniques.Categories and Subject Descriptors (according to ACM CCS): I.3.6 [Computer Graphics]: Methodoloy and Techniques
