In the medical education, a surgery simulator which is effective to train the necessary skills is greatly expected in the current social context (e.g. kindness to animals). To realize the advanced surgery simulator, various technological issues should be overcome. One is modeling of geometrical and physical characteristics of soft deformable objects. Another is modeling of topological transformations such as cutting and needle insertion. Furthermore, the real-time and interactive operation with haptic sense is required. In this paper, the above various modeling technics which make the core technologies for the surgery simulator are discussed in consideration of both reality and real-time calculation. The validity of proposed method is demonstrated by interactive simulation.
