InsertKnot(value, multiplicity)

Inserts a knot and update control point locations. Does not change parameterization or locus of curve.

Returns:: True on success, False on failure.
Return type:: bool

KnotMultiplicity(index)

Get knot multiplicity.

Parameters:: index (int) – Index of knot to query.
Returns:: The multiplicity (valence) of the knot.
Return type:: int

CreateUniformKnots(knotSpacing)

Compute a clamped, uniform knot vector based on the current degree and control point count. Does not change values of control vertices.

Parameters:: knotSpacing (float) – Spacing of subsequent knots.
Returns:: True on success, False on failure.
Return type:: bool

CreatePeriodicKnots(knotSpacing)

Compute a clamped, uniform, periodic knot vector based on the current degree and control point count. Does not change values of control vertices.

Parameters:: knotSpacing (float) – Spacing of subsequent knots.
Returns:: True on success, False on failure.
Return type:: bool

SuperfluousKnot(start)

Computes the knots that are superfluous because they are not used in NURBs evaluation. These make it appear so that the first and last surface spans are different from interior spans. http://wiki.mcneel.com/developer/onsuperfluousknot

Parameters:: start (bool) – True if the query targets the first knot. Otherwise, the last knot.
Returns:: A component.
Return type:: float
