In this paper  we propose an efficient method to generate optimal multiresolution dynamic models. By the method  we define the triangle importance degree as a weight parameter to be embedded to the edge contraction cost  so the new metric can not only measure distance error but also reflect geometric variation of local areas. A deformation degree weight is appended to the aggregated edge contraction cost for the whole animation  thus sharp features on areas with large deformation can be preserved. In addition  a process of mesh optimization and validity check can further alleviate the geometric distortion of the approximations. Our approach is efficient in operation  easy for implementation  and as a result high quality of dynamic approximations with well-preserved fine details can be generated at any given frame. 2010 IEEE.
