Although commonly used for meshing, sub-mapping method is frequently bothered by its unstable region segmentation process. Although region segmentation can be avoided with the help of recognized models, the existing algorithms of obtaining recognized models are still flawed. In order to obtain accurate recognized models and high meshing quality, a quadrilateral mesh generation method is proposed on basis of mean value interpolation. Firstly, computational coordinates of inner loop vertices are determined by mean value interpolation according to regularization result of outer loop. Secondly, under the barycenter superposition principle, surface's recognized model is obtained by use of regularization result of inner loops. Finally, facial mesh is generated via solving equations. Experiments are carried out to testify feasibility, advantage and stability of the proposed method. The results manifest that the proposed method is able to guarantee meshing quality and is applicable for quadrilateral mesh generation of multi-loop surfaces. [ABSTRACT FROM AUTHOR] |
