We describe an algorithm for constructing a Lagrange interpolation pair based on C^1 cubic splines defined on tetrahedral partitions. In particular, given a set of points V@?R^3, we construct a set P containing V and a spline space S"3^1(@?) based on

We develop a local Lagrange interpolation scheme for quartic C^1 splines on triangulations. Given an arbitrary triangulation @D, we decompose @D into pairs of neighboring triangles and add ''diagonals'' to some of these pairs. Only in exceptional cas

A trivariate Lagrange interpolation method based on C 1 cubic splines is described. The splines are defined over a special refinement of the Freudenthal partition of a cube partition. The interpolating splines are uniquely determined by data values,

We analyze the structure of trivariate C1 splines on uniform tetrahedral partitions $\Delta$. The Freudenthal partitions $\Delta$ are obtained from uniform cube partitions by using three planes with a common line to subdivide every cube into six tetr
