Semi-regular triangular mesh subdivision surface reconstruction

Focusing on mesh reconstruction problem of reverse engineering, a subdivision surface reconstruction method to reproduce a semi-regular triangular mesh while preserving the sharp feature was proposed, which can make full use of the multiresolution analysis of subdivision surface. Firstly, the base mesh was created by removing maximally the independent set of vertices after the pretreatment. Then by employing the nearest point method on the normal direction projection and considering the Loop subdivision limited position mask, iterative vertices modifications were utilized to adapt the semi-regular mesh to fit the subdivision surface. Finally, experimental results were given to illustrate the effectiveness and efficiency of the proposed method.
