O. Box 43, 3300 Eger, Hungary hofi@ektf.hu Imre Juhász Dept. Descriptive Geometry, University of Miskolc, 3515 MiskolcEgyetemváros, Hungary agtji@gold.unimiskolc.hu Bspline curves are defined in a piecewise way over a closed interval, where the interval section points are called knots. In some recent publications geometrical properties of the modification of one knot value are discussed. The aim of this paper is to describe an effect of the symmetric modification of two knots. Keywords: Bspline curve, knot modification, path. MSC: 68U05 [ Fulltextpdf (122 KB)] for subscribers only.
