1. A three-dimensional surgery simulation system for generating a three-dimensional surgery simulation result of an anatomical part undergoing a simulated surgical procedure, comprising:

  • a display unit;

    a three-dimensional visual imaging unit adapted to be worn by an operator for viewing three-dimensional images on said display unit;

    a storage unit for storing a plurality of voxelized three-dimensional model image data sets, including at least one of a pre-operation anatomical data set, a surgical instrument data set, an implant data set, and a simulation result data set;

    an input unit adapted to be operated by the operator for controlling progress of the simulated surgical procedure; and

    a computing unit coupled to said display unit, said storage unit and said input unit, said computing unit computing the simulation result data in accordance with said voxelized three-dimensional model image data sets and under the control of said input unit, and controlling said display unit to permit viewing of the surgery simulation result in three-dimensional form thereon by the operator when the operator wears said visual imaging unit;

    wherein, when said computing unit detects the surgery simulation result to have a first boundary face with a discontinuous edge that is common to at least a second boundary face, said computing unit processes the first and second boundary faces as a common closed surface, and assigns two voxels sharing the common closed surface as seeds for seed-and-flood algorithm computations during surface voxelization in the generation of the simulation result data.
