We have aimed to develop a virtual surgery system that realizes the performance of surgical maneuvers on elastic organs and to construct an elastic organ model known as sphere-filled model. In this paper we describe a new method of deforming volumetric data in real time by using sphere-filled model. As well we modified this model to take the interference between soft tissue and rigid tissue to consideration. Furthermore basic surgical maneuvers (pushing, pinching and incision) and connection with force feedback device are realized on this model similarly to our surface model.
