| Abstract: |
| Progressive meshes offer an efficient continuous-resolution representation for LoD(level of detail) modeling. In this paper, a new progressive mesh representat ion is introduced to support faster restoration and to avoid ambiguous operation s, which appear in other progressive mesh representation. As a result, more mesh types are available in this representation. In addition, a new mesh simplificat ion scheme is presented to implement the new progressive mesh representation. |
| Key words: Level of detail, mesh simplification, progressive meshes, virtual reality. |
