Volumetric Incision with Mesh Maintenance Mar 2012-Jan 2013
In this project, an incision scheme for tetrahedral mesh in virtual surgery system is proposed. A suitable scheme should be able to not only accurately model the incision, but also suppress increment in mesh complexity and decrement in mesh quality. Thus we proposed an edge-merging algorithm to eliminate elements that are too small and a mesh maintenance scheme to improve the mesh quality.
Introduction
An efficient, accurate and quality maintaining approach of modeling incision in volumetric models is critical in surgical simulation. The proposed incision schema identifies and splits the incision faces and applies an edge-merging algorithm to suppress the creation of redundant tetrahedrons. Then a mesh maintenance scheme composed of a smoothing and a swapping technique is proposed to improve the mesh
quality . The two schemes are tested separately in different scenes. Experimental results are shown to demonstrate the effectiveness of our schema for cutting in volumetric models with a low complexity and high quality mesh and its suitability in surgical simulation.
