The dual quaternion smooth skinning method is designed to eliminate these undesirable deformation effects. While linear smooth skinning allows a mesh to collapse or shrink when a bone twists, dual quaternion skinning helps to preserve volume in the mesh, creating more realistic deformation in those problem areas.
