چکیده

1. Introduction Many objects in Industrial or Conceptual Design rely on an initial set of ‘‘feature curves’’. These are the essence of the shape information for the object’s appearance. For many applications, these curves are planar, for example flow lines of a ship hull or a grid of cross sections of the roof of a car. For others, they will be 3D space curves, such as the outline of a car’s hood. Either type of curve has to be ‘‘fair’’ or ‘‘pleasant’’, thus giving rise to acceptable surfaces for the object to be designed. The question arises as to what constitutes a fair curve. Most CAD systems seem to rely on some sort of curvature information for this, and the prevailing tools are curvature combs and curvature plots. A comparison of these tools is the topic of the present paper.
