Transparent haptic rendering of the contact between a tool and its environment requires very frequent update of the contact forces acting on the tool. Given a rigid tool and a deformable environment, we define contact constraints by solving a constrained dynamic simulation problem, typ- ically at a low update rate. A generalized contact Jaco- bian defines velocities at the constraints given the velocity of the rigid tool. We define an inverse of the contact Jaco- bian that is dynamically consistent with the constraints and, once we know other forces acting on the rigid tool, it allows a fast update of the accumulated contact forces, and thereby highly transparent rendering.
