With the rapid development of recent 3D scanning and graphic modeling technique, the size of 3D model data increases drastically, which brings many challenges in its storage, display and transfers. Therefore a simplistic representation of 3D model data is in great demand. First current algorithms of dynamic mesh simplification were analyzed, and then an algorithm for mesh simplification was designed to construct topology alterable progressive mesh representation of 3D model. Based on this progressive mesh, a view dependent, compact and dynamic multiresolution structure was constructed by reorganizing the simplified model data. Finally a view dependent dynamic simplifying algorithm was presented. Theory analysis and experiment result showed that this novelty method can generate proper detailed simplified model based on view parameters, which achieved good simplification effect preserving both its geometry shape, and its attribute characters such as color etc. The presented algorithm can be widely used in many applications because of its small storage requirement, low cost and high adaptability.
