Boehm knot insertion
WebDec 1, 2006 · Extension of a B-spline curve or surface is a useful function in a CAD system. This paper presents an algorithm for extending cubic B-spline curves or surfaces to one or more target points. To keep the extension curve segment GC 2 -continuous with the original one, a family of cubic polynomial interpolation curves can be constructed. One curve is … WebBöhm knot insertion. (You do not need to memorise the formula for knot insertion.) You are also expected to know the Bézier curve material from last quarter. Rational Splines & NURBS. Equivalence with weighting. Uses with points at infinity. Conic sections, especially circular arcs, defined with degree 2 rational B-splines or rational Bézier ...
