GPU rigid skinning based on a refined skeletonization method

摘要

In this paper, we present a skeletal rigid skinning approach. First, we describe a skeleton extraction technique that producesnrefined skeletons appropriate for animation from decomposed character models. Then, to avoid the artifacts generated innprevious skinning approaches and the associated high training costs, we develop an efficient and robust rigid skinningntechnique that applies blending patches around joints. To achieve real time animation, we have adapted all steps of our rigidnskinning algorithm so that they are performed efficiently on the GPU. Finally, we present an evaluation of our methodsnagainst four criteria: efficiency, quality, scope, and robustness. Copyright © 2010 John Wiley & Sons, Ltd.
