A New C2 Rational Interpolating Model and Its Applications

Q. Duan, S. Ma, X. Duan (PRC), and E.H. Twizell (UK)


curve design, rational spline, constrained interpolation.


In this paper a new method is developed to create a smoothness interpolation using values of the function being interpolated. This is a kind of rational cubic interpolation, it not only belongs to C2 in the interpolating interval, but could also be used to constrain the shape of the interpolant curves.
