Abstract:

A subdivision connectivity remeshing method was presented for a single boundary genuszero triangular mesh. It is based on the construction of quasiconformal parameterizations of original meshes and umbrella operator smoothing with the mixed area and vertex distributing density weight. A point location method based on the partition of the rectangle was presented in order to accelerate the remeshing algorithm. According to some experiments and comparisons of some typical 3D meshes, it is obvious that our method can generate the new meshes fast, and the quality of the generated meshes with subdivision connectivity remeshing method is obviously improved compared with that of the meshes producted by the umbrella operator remeshing based on only the area weight or vertex distributing density weight.
