| Abstract: |
| In this paper, we study the constrained control of a weighted rational interpolation patch. By using the method of weighted combination, we obtain a new class of bivariate rational interpolation surfaces which the shape can be adjustable, which generalize the theoretical results of the NURBS methods in surface interpolation. |
