Abstract. Cage based deformation techniques aims to be an easy to use tool for graphics modeling, texturing and animation. In this paper we describe the most important methods, their foundations, and the desirable properties that they should satisfy. We also present a comparative to show the strong and weak points of each one, taking into account their distinctive utilities. Finally, we discuss some applications that exploit cage capabilities in order to create a more complex deformation system or to simplify other deformation techniques.
