We develop a local Lagrange interpolation scheme for quartic C 1 splines on triangulations. Given an arbitrary triangulation , we decompose into pairs of neighboring triangles and add "diagonals" to some of these pairs. Only in exceptional cases, a few triangles are split. Based on this simple refin
