Abstract : Contact handling is the key of deformable objects simulation, since without it, objects can not interact with their environment nor with the user. In this paper, we propose a novel and very efficient approach for precise computation of contact response between various types of objects commonly used in computer animation. Being constraint based, this method ensures physical correctness, and respects Singorini s law. It can be used with any deformation model, and is based on the use of the initial compliance matrix and contact warping. Thus, the contact response can be computed efficiently, and the object deformation can still be done in a physically plausible way provided the underlying model is physical.
