Surface interpolation with tension controls using cardinal bases
The authors present the cardinal product method using the weighted \(\nu\)- splines of the first author [ACM Trans. Math. Softw. 13, pp. 68-96 (1987; Zbl 0626.65008)], which forms a parametric surface interpolant to a given rectangular set of control points. The shape of the resulting piecewise bicubic surface can be interactively changed by manipulating the control points or by modifying the interval or point tension parameters. Two examples and comparisons with other methods are given.
