This paper presents a skeletal rigid skinning approach. First, a skeleton extraction technique is introduced that produces refined skeletons appropriate for skinning. Then, to avoid shortcomings of previous skinning approaches, an efficient and robust rigid skinning technique is developed that applies blending patches around joints. To achieve real time animation, all steps of the rigid skinning algorithm have been ported on the GPU. Finally, an evaluation of the proposed techniques is presented against four criteria: performance, quality, scope, and robustness.
