We propose an innovative approach to feature-preserving 3D thumbnail creation in this research. The 3D thumbnail system aims to help the user efficiently browse 3D models in a large 3D database. The user can browse multiple 3D models with pre-generated 3D thumbnails, and view them from different angles interactively. The 3D thumbnail is a simplified version of the original model and requires much less memory and time to render. In the proposed system, we separate the framework into offline and online two processes for improving the run-time performance. Two types of descriptors of each 3D model are first generated offline and, then, the thumbnail result can be quickly rendered online using these pre-generated descriptors. Preliminary experimental results are given to demonstrate the proposed methodology.
