Realistic Skeleton Driven Skin Deformation

Skeleton driven animation is a popular method for the animation of deformable human and creature characters. The main advantage is its computational performance. However it suffers from a number of problems, such as collapsing elbow and candy wrapper joint. In this paper, we present a new method which is able to solve these defects; reduce the animator's manual work still allowing his/her full control over the process; and realistically simulate the fat bulge effect around a joint.
