%X Availability of commodity physics engines such as PhysX¡¯s nVidia has significantly reduced the effort required for developing interactive applications concerning the simulation of the physical world. However, it becomes a problem when force feedback is needed since the addition of haptic rendering into these applications is non-trivial. The issues include the high haptic update rate and the inaccessibility of force data in the physics engine. In the paper, we tackle the first issue by mediating the update-rate disparity between haptic rendering and other processes by data buffering, and the second issue by calculating the force feedback indirectly using the engine¡¯s collision geometry data. The major benefit of these techniques is that they enable a homogeneous development environment where the same engine can be used for both the physics and haptic simulation. Furthermore, integration of force feedback into physics-engine based applications would not introduce significant changes into developer¡¯s codebase. The proposed techniques have potential to streamline the development of demanding applications such as virtual surgical simulation and immersive computer gaming.
