| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 89 === In this paper, we proposed a multiresolution model editing approach applying on unstructured triangulated meshes. The proposed approach is an extension application of multiresolution modeling. We build a multiresolution representation for a triangulated mesh and then modify the mesh without pre-processing on the given mesh. The proposed approach consists of three components : (i) fine-to-coarse hierarchy, (ii) discrete fairing, and (iii) details encoding. The fine-to-coarse hierarchy is used to build a multiresolution representatation for a selected region on a mesh. The difference between two adjacent hierarchical levels of the multiresolution is obtained and recorded by the discrete fairing and details encoding. We modify a coarser mesh and then construct the modified fineset-resolution mesh based on the recorded information.
In our system, a user can select an arbitrary region consisting of triangles for modification with the multiresolution modeling approach. We can preserve the detail information of the global shape during the modification without any special basis functions or complicated methods.
