Abstract
Asymmetric animation links control motion propagation through motion element graphs of models. Asymmetric animation links have direction attributes. When a motion element is moved, the influence of this motion propagates away from this motion element through the motion element graph. Upon reaching an asymmetric animation link, if the direction of motion propagation through the graph matches the forward direction of the asymmetric animation link, this motion will pass through the asymmetric animation link to potentially influence additional motion elements. If the motion propagates through the graph in the reverse direction of an asymmetric animation link, then the asymmetric animation link will block the motion from traveling past the asymmetric animation link. Asymmetric animation links can be added or removed from models and can connect two or more models. Additionally, the direction attribute of an asymmetric animation link may be reversed as needed to change the behavior of the motion element.
