This paper is concerned with a real-time method for realizing virtual destruction of a 3D object with external force. A target object is a soft tofu (bean curd) cube which is easily destructable or breakable with a stick. A spring-mass network model is used to represent such an object. Destruction is realized by cutting a spring when its length exceeds its maximum length due to excess stretch force. A system was implemented on a PC with 2 CPU’s and a PHANToM, a force feedback device. A set of optimal parameters are experimentally identified. It is concluded that real-time destruction realized with the presented method can provide destruction close to real one.
