Abstract

Polygonal surface models are generally composed of a large amount of polygonal patches. Highly complex models can provide a convincing level of realism but rather cause problems in real-time applications, such as virtual reality or 3D simulation system focusing on real-time interactivity. Therefore, it is useful to have various simplified versions of the model according to the performance of the system. In this paper, we present a surface simplification algorithm, which can excellently preserve the characteristic features of the original model, even after drastic simplification process. In addition, the proposed algorithm is efficient in memory usage and useful in real-time rendering applications requiring progressive and incremental rendering of surface data.
