Zusammenfassung
In dieser Arbeit bestimmen wir die B-Spline-Koeffizienten und Knoten einer B-Spline-Kurve, die die gleiche Gestalt wie eine vorgegebene segmentierte Bézier-Kurve besitzt. Die Stetigkeitsordnung in verschiedenen Bézier-Segment-Übergängen kann dabei unterschiedlich sein.
Abstract
In this paper we determine the coefficients and knots of a B-spline curve, which has the same shape as a given segmented Bézier curve. The order of continuity in different joins of Bézier segments may be different.
