A method of bivariate interpolation and smooth surface fitting is developed for rapidly varying z values given at points irregularly distributed in the x-y plane. The surface is constructed by means of C’ triangular interpolants defined on a triangulation of the convex hull of the points set. The needed partial derivative values are estimated by a new… CONTINUE READING
