Title: New method of generating quadrilateral curvilinear meshes from triangular model
Abstract: Quadrilateral partition on triangular meshes data is the primary process of composite surface modeling.A novel method of quadrilateral partition on cloudy manifold triangular meshes is presented,which is based on algorithms of mesh simplification and harmonic mapping.Simplification technology grounded in removing vertexes is adopted to simplify triangular mesh model;and then quadrilateral partition is gained by mapping the simplified mesh to 2D parameter domain through harmonic map.By inverse mapping the gained data to 3D space and geodesic technology,3D quadrilateral topological partition,fitting composite curve modeling,is eventually implemented.This method is simple,practical and has high operation speed.Real illustrations demonstrate that it is effective and feasible.
