A Curvature Flow Based Fairing Algorithm of Quad-Dominant Meshes
Hu Shi · Chinese Journal of Computers · 2008
Mesh model is the most extensively used 3D geometry representation in computer graphics and geometry processing.Quadrilateral/quad-dominant mesh has the unique advantage of representing 3D shapes because its structure fits the shape variation well according to human perception.Moreover,quadrilateral mesh can be directly applied to various fields as geometric modeling,subdivision surface and architecture design.This paper presents a differential properties based fairing algorithm on quad-dominant meshes.The method is computationally efficient and very easy to implement.During the fairing process,geometric features on the mesh model can be well preserved because of the geometry diffusion guided by curvature flow.T-junctions in the mesh structure are also under special consideration.
