Résumé: This paper addresses the problem of decomposing a polyhedral surface into ‘‘meaningful ’’patches. We describe two decomposition algorithms —.ooding convex decomposition and watershed decomposition, and show experimental results. Moreover, we discuss three applications which can highly bene .t from surface decomposition. These applications include content- based retrieval of three- dimensional models, metamorphosis of three- dimensional models and simpli .cation.
