| 摘 要： | 0 Introduction By using a subdivision rule a control mesh will be refined withincreased detail . Asequence of subdivisions then produces a hierarchyof surfaces withincreasingreso- lution.Such a hierarchy allows the selection of a repre- sentation of surface at a particularlevel of detail ,whichis useful in many applications in both modeling and render- ing, such as view dependent rendering and progressive transmission. This paper introduces a newreverse Loop subdivision algorithm which can re…

| Abstract: | In this paper we introduce a new reverse Loop subdivision method. In contrast to current wavelets based Loop subdivision scheme, our method applies the same rules to both regular and extraordinary vertices and reconstructs the sharp features easily. Furthermore, our method runs faster because it does not need analysis and synthesis procedural. Our main goal is the design of a reverse subdivision method that can reconstruct the coarser mesh from a finer subdivision surface with sharp features for multiresolution representation. The proposed method only needs a little memory storage and brings little error, and it is easy to implement. |
