A method and system for constructing a skeleton for use in animation models allows definition of a skeleton with non-articulated chain elements. These non-chain elements can be 3D objects, which can be rendered and visible in final images and animations, or null models which are not visible in final images or animations. All of the elements of the skeleton, including non-chain elements, are arranged into a skeleton hierarchy. The skeleton hierarchy can include articulated chain elements, articulated chain elements combined with non-chain elements, or solely non-chain elements. Relational information and/or mathematical relationships can be defined for the elements of the skeleton to define ranges of motion, elements which move with other elements and/or translation, rotation, scaling and/or animation of elements.
