Mj. Lai et Ll. Schumaker, SCATTERED DATA INTERPOLATION USING C-2 SUPERSPLINES OF DEGREE-6, SIAM journal on numerical analysis, 34(3), 1997, pp. 905-921
We show how C-2 supersplines of degree six can be used to interpolate
Hermite data at the vertices of a quadrangulation. We also present err
or bounds that show that our method has full approximation order seven
, and compare its efficiency with other C-2 interpolation methods in t
he literature.
