Compared to the extensive works on static model approximation  very little attentions have been paid to animated models. In this paper  we propose a new method to approximate animated models with local area distortion and deformation degree control. Our method uses an improved quadric error metric guided by a local area distortion measurement as a basic hierarchy. Also  we define a deformation degree parameter to be embedded into the aggregated quadric errors  so areas with large deformation during the animation can be successfully preserved. Finally  a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast  easy to implement  and as a result good quality dynamic approximations with well-preserved sharp features can be generated at any given frame. 2010 SPIE.
