Example based skinning with progressively optimized support joints

Skeleton-Subspace Deformation (SSD), which is the most popular method for articulated character animation, often causes some artifacts. Animators have to edit mesh each time, which is seriously tedious and time-consuming. So example based skinning has been proposed. It employs edited mesh as target poses and generates plausible animation efficiently. In this technique, character mesh should be deformed to accurately fit target poses. Mohr et al. [2003] introduced additional joints. They expect animators to embed skeleton precisely.
