                         and deformable objects. These are represented as groups of 
                         particles linked by linear constraints, while a Verlet integrator 
                         is used for motion computation. Unlike traditional approaches, we 
                         accomplish physical simulation without explicitly computing 
                         orientation matrices, torques or inertia tensors. The main 
                         contribution of our work is related to the way collisions are 
                         handled by the system, which employs different approaches for 
                         deformable and rigid bodies. In particular, we show how collision 
                         detection using the GJK algorithm and bounding sphere hierarchies 
                         can be combined with the projection based collision response 
                         technique described by Jakobsen.",
