Embodiment approach

[0037] The biological rib nose and mandible simulation plastic technology based on artificial bone repair materials extends the deformation method based on Laplace coordinates on the surface mesh to the body mesh, and obtains high-quality images in a simple and convenient interactive operation mode. The body mesh deformation effect keeps the geometric details and model volume unchanged as much as possible, and at the same time fully considers the influence of non-uniform material parameters on deformation to obtain an effect similar to physical deformation.

[0038] Represent the input tetrahedral mesh as a two-tuple, M=(P,K), where P{p i∈ R 3 I1≤i ≤N} is the electric shock in the three-dimensional Euclidean space; K=V∪E∪F∪T is an abstract simplicial complex, which describes all adjacency information of a player, including the vertex set V={iI1≤i≤N} , edge subset E={i, j}, face subset F={(i, j, k)}, and tetrahedron subset T={(i, j, p, q)}. Similar to the definition on the su...

Abstract

The invention provides a biological rib nose and lower jaw simulation plastic technology based on an artificial bone repair material. A deformation method based on the Laplace coordinates on the surface grid is popularized to the volume grid; under a simple and convenient interactive operation mode, a high-quality volume grid deformation effect is obtained, geometric detail features and model volume are kept unchanged as much as possible, and meanwhile, the influence of non-uniform material parameters on deformation is fully considered, so that an effect similar to physical deformation is obtained; by improving an existing shaping technology, the technology has the advantages of being high in calculation precision, good in effect and beneficial to application and popularization, and therefore the problems and defects of the technology in one item of the background technology are effectively solved.

Description

technical field [0001] The invention relates to the technical field of plastic surgery, and more specifically relates to the bio-rib nose and mandibular simulation plastic technology based on artificial bone repair materials. Background technique [0002] Using computer-aided facial plastic surgery simulation, doctors can plan preoperative surgery, choose the optimal surgical plan and surgical steps, train the judgment and decision-making ability during surgery, and improve the proficiency of on-the-spot operations; at the same time, accurate prediction of postoperative results is beneficial to patients It has a very important psychological effect and is of great significance to the communication between doctors and patients. It has always been the frontier and hot spot of multidisciplinary research such as computer and medicine. [0003] Through the research and exploration of the general plastic surgery simulation system, it is found that the key deformation technology is ...
