ContextNURBS and B-Spline curves are defined as knot vectors. To define NURBS and B-Spline faces, a knot vector is required for each parameter direction. A knot vector is a sequence of real numbers used to define:
Note:
If knots coincide, they are called multiple knots, or multiple weighting of
knots.
If you transfer knots to a system with larger tolerances, knots that are too close to each other can become multiple knots. Multiple knots have an impact on the number and continuity of face segments. This can lead to undesirable changes in the continuity of the curve and in the internal continuity within the face.
