Comparison of Implicit Skinning with our new Elastic Implicit Skinning. From right to left: Jeff in T-pose, Jeff rigged with implicit skinning, Jeff rigged with elastic implicit skinning, female model with implicit skinning then elastic implicit skinning.

With elastic implicit skinning the skin stretches automatically (without skinning weights) and the vertices distribution is more pleasing (notice the belly button stretch). Our approach is more robust, for instance the angle's range of joints is larger than implicit skinning (notice the triangle inversion of implicit skinning at the knee joint)
