When dealing with irregularly distributed data points, the former are usually cumbersome whereas the later may present continuity problems. In the present paper, a global surface interpolation method is presented. Continuity is assured up to the second partial derivatives, and arbitrarily placed data points are admitted. Complexity of the algorithm is discussed, together with the possibility of interactively varying the interpolant's shape.10.2312/eg.19801004
