Free-Form Surface Construction in a Commercial CAD/CAM System,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.

,Conversion of Dupin Cyclide Patches into Rational Biquadratic Bézier Form,This paper uses the symmetry properties of circles and Bernstein polynomials to establish a series of interesting . of rational biquadratic Bézier patches. A robust algorithm is presented, based on these properties, for the conversion of Dupin cyclide patches into Bézier form. A set of conversion examples illustrates the use of this algorithm.

On Normals and Control Nets,This paper characterizes when the normals of a spline curve or spline surface lie in the more easily computed cone of the normals of the segments of the spline control net.
