Abstract: |
By using technique of Bézier-method, Hermite interpolation schemes are constructed based on cubic splines on Wang's refined triangulations. The existence and the uniqueness of the interpolation are discussed. The interpolant has local support and explicit representation. |
Key words: refined triangulation bivariate cubic spline Hermite interpolation local basis |
