Geometric continuity, shape parameters, and geometric constructions for Catmull-Rom splines Tony D. DeRose, Brian A. Barsky January 1988 Catmull-Rom splines have local control, can be either approximating or interpolating, and are efficiently computable. Experience with Beta-splines has shown that it is useful to endow a spline with shape parameters, used to modify the shape of the curve or surface independently of the defining control vertices. Thus it is ... [more] Available in Transactions on Graphics, Vol 7, No 1, January 1988. |
