It ignores the basic realistic method of defining the skeleton in terms of joint center, and connecting segments arranged in a natural hierarchy that allow animation by rotation of joint centers to provide a pose and transplation of the root joint, to transport the entire character. This is the way it is done “under to covers” of the skeleton-cased animation tools and is the best known and understood basic for providing the skeleton and geometry animations. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The comments about never this and not that are made from the vantage point of a barely understood glimps at some highly abstracted human interface for some tool.
