Bone drilling is a fundamental task in several surgical procedures, including mastoidectomy, cochlear implantation, orbital surgery. It consists in eroding the part of file bone in contact with the tip of the surgical tool when a sufficient pressure is exerted. Since the bone is all almost rigid material, the bone drilling simulations usually employ voxel-based representations of the bone, so that it is easy to show material removal by playing with material density in the voxels. Unfortunately, there are cases in which drilling is only a part of file task, and parts of the same object are also cut away or worse, the bone is slightly deformable and therefore voxel-based representations do not work, well. We propose a novel method to simulate drilling oil objects represented explicitly by means of a tetrahedral mesh. The key, idea of our method is to create all alternative representation of the tetrahedron when it is partially eroded. Such representation consists of a set of smaller tetrahedra obtained by a hierarchical decomposition of file original one, and combined to represent the current status of the erosion. |
