The notions of Nef polyhedron, locally adjoined pyramid and face of a Nef polyhedron are carefully explained. Data structures for representing Nef polyhedra are discussed, a

Besides its extreme simplicity and robustness, this spline (in the cardinal case) deserves some interest because of its affine invariance. This allows a complete analysis of its shape-preserving properties, which is given

Instead our new algorithm is based on the idea of subsequently changing one control point of a given B-spline curve so that the new curve minimizes the integral of the squared /-th derivative of the B-spline curve.

In this paper, an investigation into the nature of this integration problem is performed, followed by the specification of a series of requirements on CAD systems to support it. Guided by these pragmatic requirements, we present an approa
