| Abstract: |
| An algorithm for triangle mesh simplification based on super-envelopes is presented in this paper. This algorithm can not only deal with arbitrary meshes, but also control the global error bound of the simplification. It runs fast and the result is perfect. The authors also give a method for constructing continuous level of detail models. Examples illustrate efficiency of the algorithm. Finally, the authors compare the algorithm with those algorithms with global error control. |
