摘要	In computer graphics, animated models are widely used to represent time-varying data. In this paper, we propose an improved method to generate multiresolution animation models. We use a curvature sensitive quadric error metric (QEM) criterion as our basic measurement, which can preserve local features on the surface. We append a deformation weight to the aggregated edge contraction cost for the whole animation to preserve areas with large deformation. At last, we introduce a mesh optimization method to deal with the animation sequence, which can efficiently improve the temporal coherence and reduce visual artifacts. The results show our approach is efficient, easy to implement, and good quality progressive animation models can be generated at any level of detail. © 2009 IEEE.
