Optimal Multiresolution Dynamic Models Generation Based on Triangle Importance

摘要：

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 wellpreserved fine details can be generated at any given frame.
