Abstract

Collision detection and force computation between complex geometries are essential technologies for virtual reality and robotic applications. Penalty-based haptic rendering algorithms provide a fast collision computation solution, but they cannot avoid the undesired interpenetration between virtual objects, and have difficulties with thin non-watertight geometries. God object methods or constraint-based haptic rendering approaches have shown to solve this problem, but are typically complex to implement and computationally expensive. This paper presents an easy-to-implement god object approach applied to six-DoF penalty-based haptic rendering algorithms. Contact regions are synthesized to penalty force and torque values and these are used to compute the position of the god object on the surface. Then, the pose of this surface proxy is used to render stiff and stable six-DoF contacts with friction. Independently of the complexity of the used geometries, our implementation runs in only around 5 us and the results show a maximal penetration error of the resolution used in the penalty-based haptic rendering algorithm.
