Abstract: In this paper, we propose a skinning approach for the virtual hand deformation. This is an implicit skinning approach based on the spherical primitives. Our approach presents a new idea of skinning, which aims to correct the undesirable effects introduced by geometric skinning techniques such as linear blending skinning (LBS) or dual quaternions skinning (DQS). In this paper, we propose the use of volumetric shape as a new geometric representation to better capture the behaviour of the skin. We present a real-time method producing a deformation of the mesh which takes into account the contact of the skin and the simulation of the muscles swelling. Our hand mesh is approximated with a volumetric structure which allows us to deform it in a plausible way while dealing with collisions and retaining the mesh details.
