Interactive Techniques for Correcting CAD/CAM Data

Author(s): Jean, B. A.; Hamann, Bernd | Editor(s): Weatherill, N. P.; Eisemann, P.; Haeuser, J.; Thompson, J. F. | Abstract: The paper presents a technique for correcting discontinuites (holes, overlapping surfaces, and intersecting surfaces) in CAD data. The technique approximates faulty geometries by several new B-spline surfaces which match properly. Each B-spline surface is constructed from four user-defined boundary curves.
