Zusammenfassung

Die Konstruktion verbindet die Vorteile der Kurvendarstellung von Bézier mit denen derB-Splines, für deren Entwicklung nach Bernstein-Polynomen ein einfacher Algorithmus angegeben wird. Damit zerfällt der bekannte Algorithmus von de Boor zur Bestimmung der Splinepunkte in zwei Teile: eine vom Kurvenpunkt unabhängige Bestimmung der Koeffizienten der Entwicklung und eine von der Segmentierung unabhängige Bestimmung der Kurvenpunkte.

Abstract

The construction combines the advantages of Bézier representation with those ofB-splines. A simple algorithm calculates the Bézier polygon from nodes. Hence the wellknown algorithm of the Boor decomposes into two parts: the calculation of the Bźier polygons, independent of the curve points, and the calculation of the curve points, independent of the segmentation.
