Abstract	Physical based simulations of deformable scenes require very high computational power but ensure realism and, if interactive, allow the haptic rendering to the user. Modern graphics processing units provide enough power to simulate complex models. Thanks to this achievement GPU based haptic simulators are gaining popularity, however, the correct timing of simulations and rendering still represents a neglected aspect of interactive physical simulations. In this work we propose a new method that enhances the computation of interactive deformable scenes on GPU by introducing remote rendering. The method improves the timings of physics simulation, thus leading to more realistic and stable interactive simulations. Moreover, the proposed method allows to increase the complexity of the graphic rendering engine used without any side effects on the physical simulation. Stereoscopic rendering and scene broadcasting can take advantage form this new technique. We applied the proposed method to our GPU based surgical simulator: analysis and preliminary results are presented.
