The author considers a three-dimensional domain which is tesselated into tetrahedra. He constructs a \({\mathcal C}^ 1\) interpolant for \({\mathcal C}^ 2\) data, that is a generalization of the well-known bivariate Clough- Tocher scheme. The interpolant is local, piecewise polynomial and has cubic precision. Some computational aspects are discussed.
