Remeshing Driven by Smooth-Surface Approximation of Mesh Nodes

This paper presents improvements in surface mesh of models generated by Boolean and assembly operations or surface reconstruction methods. The general concept consists of applying local mesh modification operators on the surface mesh to improve the shape quality of the elements without losing geometric information. To guarantee the model geometric characteristics, a smooth surface approximation of the model is evaluated and coupled to the operators of local mesh modifications. The approximation uses mesh information to generate the B-splines patches
