We present a parameterized representation of virtual organs for surgery simulation purpose. Random 3D input mesh are parameterized and resampled into a regular 2D parameterized model. With this parameterized representation, a high resolution 3D organ mesh can be reconstructed and deformed interactively with a simple and fast free-form deformation method. The amount of deformation and force feed-back can be calculated rapidly. Therefore, haptic rendering can be achieved. In addition, the parameterized mesh can be used to handle collision detection and the contact between multi-objects in an efficient way. With the parameterized mesh, realistic visual and haptic rendering can be provided for interactive surgery simulation.
