Wellesley, Massachusetts, А К Peters, Ltd., 1995. - 308 p., ISBN 1-56881-017-2.Library of Congress Cataloging-in-Publication Data. This is the continuation of __One Dimensional Spline Interpolation Algorithms__ to two dimensions as mentioned in the postscript to that book. We again take the point of view that the nodes (only in the plane) and the values to be interpolated are fixed ahead of time and that no information on a possible underlying function is available.

Polynomial Interpolation on Special Triangular Grids.**Bilinear Spline Interpolation.** Searching a Rectangular Grid. Bilinear Interpolation on Rectangles.**Biquadratic Spline Interpolants.** Knots the Same as Nodes. Knots Different from Nodes. Shape Preservation.

This book presents a practical introduction to computing spline functions, the fundamental tools for fitting curves and surfaces in computer-aided design (CAD) and computer graphics. It provides detailed derivations of the formulas needed for a computer implementation of the interpolation methods. These volumes present a practical introduction to computing spline functions, the fundamental tools for fitting curves and surfaces in computer-aided deisgn (CAD) and computer graphics.
