Abstract
Animation controls according to the present invention introduce a predictable level of control for animation without the need for iterating the simulation. Controls include shape controls that permit the effect of the simulation to be overridden for cloth and soft body materials. The effect of shape tacks are to control the local shape of objects such as cloth and soft body materials, the shape may be weighted and time varying. Shape tacking is relative to the reference coordinate system of the object being shaped. Position tacks provide control in absolute space and permit accurate placement of an object to be animated overriding the control of the simulation.
