Many methods to simulate rigid body motion and collision have been developed in the computer graphics field recently. In most methods, polygons are used to represent a rigid body configuration. In this paper a novel particle based method is presented and some examples are calculated. A simple algorithm for collision detection is proposed using particles and Distinct Element Method (DEM) is used for collision response. In the case that a configuration of a rigid body is complicated, the quantity of data is reduced and the calculation is fast. It is also easy to couple with fluid motion using Moving Particle Semi-implicit (MPS) method.
