Abstract:

This paper is a survey of methods for fitting a surface to a set of data scattered throughout a plane region. The methods surveyed include interpolation, smoothing, least-squares, and a variety of other direct and approximation methods. The fitting functions include polynomials, rationals, splines, and others. Numerical methods are emphasized, and contouring is also discussed.
