Lagrange interpolations using bivariate C2 C 2 quintic supersplines on double CloughTocher refinements
In this paper, a local Lagrange interpolation set for a bivariate quintic superspline space defined on the triangulation ?  D C T is constructed, where ?  D C T can be gained through refining certain triangles in an arbitrary regular triangulation ? ? by double CloughTocher refinements.
