Accurately Detecting Symmetries of 3D Shapes
Résumé
Many shapes and geometrical models exhibit symmetries. These symmetries are sometimes explicitly represented in the model. However, symmetry information is often lost in automatic transla- tions between file formats. Using symmetries, one can, for example, manipulate models through coherent re-meshing or intelligent mesh editing programs. We present two algorithms that automatically retrieve symmetries in a 3D model through the use of an intermediate set of functions: The Generalized Even Moments
