【Abstract】 The paper mainly describes a touch simulation method on a particle in virtual reality, which simulates some simple touch forces by controlling the displacement and direction. First the paper introduces the structure of a touch simulation device designed by our team briefly and the process of touch simulation, then discusses the basic principles and the method of some touch forces simulation. It presents some important problems and their resolutions during the simulation in details, such as the particle’s penetrating virtual objects and the acceleration of collision detection.更多还原
