Two Dimensional Spline Interpolation Algorithms

Splines are the fundamental tools for fitting curves and surfaces in computer-aided design and computer graphics. This volume presents a practical introduction to computing spline functions and takes the elementary and directly available approach of using explicit and easily evaluated forms of the spline interpolants. Spath outlines the conditions under which splines can be best applied and integrates into his presentation numerous formulas and algorithms to emphasize his concepts. He also includes FORTRAN-77 subroutines which can be applied to the abundant problems illustrated and treated in the book which in turn allows the reader to assess the performance of various spline interpolants based on the configuration of the data. A program disc is available to supplement the text and there is also a companion volume, "One Dimensional Spline Interpolation Algorithms".
