Evaluation of Optimised Centres of Rotation Skinning

In this paper, we evaluate the real-time skeletal skinning technique Optimised Centres of Rotation Skinning (CRS) in terms of animation quality and efficiency. Skeletal animation rigidly deforms static meshes, letting them perform rigid movements without requiring additional geometry and make it a core part of movies and video games. Linear Blend Skinning (LBS) is the simplest and most intuitive implementation for appropriate vertex transformation. The popular extension Dual Quaternion Skinning (DQS) resolves the volume loss of LBS but introduces new artefacts. These are addressed by the recent CRS showing promising results. Our source code for LBS, DQS and especially CRS will be made public on our website.
