Triangular Mesh Segmentation System For Hexahedron Mesh

In the past 20 or 30 years,the research on the automatic generation of structured hexahedron mesh has become more and more important.At present,the automatic generation of structured hexahedron mesh is realized based on the leaf theory algorithm of grid surface.In the process of generating hexahedron meshes with geometric branches on curved surfaces,it is necessary to carry out feature preservingIn this paper,a triangular mesh segmentation system suitable for Hexahedron meshes is constructed.In this paper,an improved thermonuclear mapping algorithm is proposed by studying the thermonuclear mapping algorithm and detecting the geometric branches of the thermonuclear mapping through Laplace spectrum behavior analysis.Secondly,based on the harmonic field contour algorithm,a simple interactive 3d mesh segmentation tool is developed.Users can obtain a better triangular mesh segmentation effect by simple stroke operation.Finally,the Hodge algorithm in the method of vector field decomposition is used to decompose the vector field of triangular mesh to analyze the surface,generate quadrangular mesh of the surface,and assist the generation of hexahedron mesh.The system constructed in this paper has passed the test case of hexahedron mesh.The experiment proves that the system is efficient and feasible,which lays a foundation for the subsequent hexahedron mesh generation.
