%X We present a simplified approach for animation of geometrically complex deformable objects represented as tetrahedral meshes. Our prototype system detects and responds to collisions of objects subject to elastic deformations of variable stiffness. The proposed approach combines several techniques, namely, collision detection using a spatial hashed grid {Teschner2003}, consistent penetration depth using propagation {Heidelberger2004}, contact surface computed according to {Spillman2005} and projection {Jakobsen2001}, the animation is based in a modal analysis scheme using an explicit-implicit integrator as in {Muller2005}. Preliminary results show that collisions between objects containing several thousand tetrahedra can be animated in real-time.
