碩士 === 國立臺灣科技大學 === 資訊工程系 === 100 === Remeshing is the basic technique which reconstructs the surfaceof 3D models for many applications among the computer graphics andvisualization techniques. In this paper, we propose a novel remeshing method based on the skeleton of 3D model. The proposedremeshing method first extracts the skeleton of 3D model by usingthe mesh contraction. According to the skeleton, the 3D model ispartitioned into several kinds of divisions. Then, line field designis applied on the surface of each division to generate the newquadrilateral mesh. Unlike the conventional remeshing method, theproposedremeshing method automatically partitions the 3D modelbased on the skeleton instead of assigning patches by user. On theother hand, the proposed method also automatically controls wherethe singularities occur to prevent the drawback of singularities. Inaddition, We demonstrate that the proposed remeshing method couldimprove the 3D model quality for 3D movies, 3D animations, and manykinds of 3D applications.
