This paper introduces a new multilevel approach for controlling the response of a deformable object to external forces. The user specifies the amount of flexibility or stiffness of the surface by controlling how the applied forces propagate through the levels of a multi-resolution representation of the object. A wide range of surface behaviour is possible, and rigid motion is attained without resort to special numerical methods. This technique is applied to the displacement constraints method of Gascuel and Gascuel to provide explicit graduated control of the response of a deformable object to imposed forces.
