ab: Summary: A new power extension factor is constructed for improving
    free-form deformation of parametric curves. The new extension factor
    has the excellence of existed extension factors and can achieve its
    maximum in the region. The closure property can be kept in the
    deformations of Bézier and NURBS curves. The deformation of a curve is
    achieved through multiplying the equation of the curve by the extension
    factor. And by interactively modifying control parameters, the outside
    of object can be described well. Experiments show that the method is
    simple, intuitive and easy to control, and desired deformations can be
    easily achieved. The method can be used in many fields such as
    geometric modeling and computer animation.
