Constructing virtual reality (VR) system has become easy and possible since low-cost and high-performance hardware becomes popular. The VR technology is expected for various kinds of application such as virtual museum, medical engineering, education, video games and other graphic activities. One of the expected applications is virtual touching on an object that we cannot touch usually. For instance, it is impossible to touch cultural assets exhibited in historical museums. If it becomes possible to pick them up in order to see the part where visitors could not see, they will get much more information from the assets, compared to the case when they just look at them. One solution is to construct the system enabling to touch an object virtually by using the VR technology. In this paper, we investigate the calculation performance to construct the VR system that uses the collision detection with a PC cluster. Our technique realizes collision with a complex object that has a large number of polygons at high speed. When the model of a hand is moved using a haptic device, quick response upon collision is realized as a PC cluster processes collision calculation.
