— This paper presents some issues in the simulation of deformable objects with force feedback. It presents an overview of our experience towards the conception of a virtual reality medical simulator. We briefly describe and discusse some well known physical simulation models such as : mass-spring networks , finite element method (FEM) and a recently long(More)
Previous works have presented solutions for stability problems arising from the diierence between the sampling rate requirements for haptic devices (about 1 KHz) and the update rates of the physical objects being simulated (about 10 Hz). These methods work well when the objects are convex and non-deformable but when the object is deformable these methods(More)

This paper presents some problems and solutions in the domain of dynamic simulation and 3D interaction in virtual reality. First, we handle the trade-off problem between precision and interactivity for the dynamic simulation of a large number of moving solid bodies. Next, in the framework of deformable object interactions we introduce a 3D cutting algorithm(More)
