ABSTRACT
In the field of scientific computing visualization, visual reality, computer animation and so on, shape metamorphosis is a very important research direction. This paper proposes a new nonlinear method of shape metamorphosis based on the bivariate vector valued rational interpolation. With the method, we can realize metamorphosis among series of polygons. First, construct a Newton-Thiele's vector valued interpolation surface for the coordinates of multiple polygons, then interpolation surface is resampled by this function, and finally get the metamorphosis polygons. The experimental results show that this method has better precision of calculation, easiness of programming as well.

A Surface Modeling Method by Using $$C^2$$C2 Piecewise Rational Spline Interpolation
A piecewise bivariate rational spline interpolation is presented only based on the values of the interpolated function. The interpolation has the following advantages: it is $$C^2$$C2 continuous in the whole interpolating region; the interpolation ...
