A method for generating cut surface in surgery simulation

This paper presents a method for generating a cut surface of a deformable object, which is rendered by a electrical instrument in surgery simulation. Meshfree methods are employed to simulate the deformation of the sof body objects. A mesh generation method is proposed to provide a cut surface generated by electrical cutting. Th proposed method is based on the idea that element deletion can be classified into cases of intersection between th meshless deformable model and the electrical instrument. Boundary smoothing and mesh refinement are included t improve the quality of generated surface. The proposed method provides simplicity in implementation, stability during progressive cutting, and efficiency in computation cost.
