In the practical application of virtual reality technology, such as surgical simulation, feedback of force is strongly needed and various force feedback devices have been developed. However, for the interaction with the virtual object using force, not only the interface device but also the kinetic model of the object must be implemented. In this paper, calculation methods of elastic virtual object model are discussed.The simulation algorithm of the transformation can be divided in two parts: the transformation model and the solving method. In our algorithm, we combined the physical elastic model with the differential solving method. The physical elastic model allows us to define the elasticity of the model by physical parameters, and the differential solving method provides us short simulation cycle time that is essential to the real-time interaction interface.A prototype environment to interact with the proposed model through 3d pointing device was developed. By the prototype, real-time operations such as pulling and cutting on to the model was proved to be possible.
