Skinning techniques are essential for character articulation in 3D computer animation. Currently, skeleton-based methods are widely used in the animation industry for its simplicity and efficiency, especially in linear blend skinning (LBS) and dual quaternion skinning (DQS). However, owing to the lack of the inside volumetric representation, they suffer from joint collapse, candy-wrapper, and bulging problems.
