Free-Form Surface Construction in a Commercial CAD/CAM System
In automobile industry, free-form surfaces often have to be constructed and even more often have to be modified. Frequently, a surface model is given as a triangular mesh, which is converted to (polynomial) spline surfaces (reverse engineering). We show some arising problems and how they are solved in our software. Furthermore, we present some open theoretical problems.
