%X In this paper, a Boolean sum algorithm is presented for constructing C~2 interpolat- ing functions over an arbitrary triangle. The algorithm is simple to construct and easy to calculate, and its approximation order O(h~(12)); its algebraic precision set includes all polynomials of degree >11. Finally, an example is given.
