ABSTRACT
This paper reports on an interactive system for manipulating a tensor-product B-spline approximation to field data for applications in which contours are of interest. The features of the system are: an interpolation technique for approximating fields defined from scattered or gridded data by tensor-product B-splines, an interactive display providing control-vertex manipulation of the resulting B-spline approximation, and a contouring algorithm that is designed specifically for B-spline surfaces.

The Interactive Editing and Contouring of Empirical Fields
A system for the interactive editing and contouring of surfaces derived from empirical fields is described. The approach taken begins with the representation of a field as a general-order, nonuniform, tensor-product, B-spline surface. It provides an ...
