API Reference > geometry-core > Bspline > BSplineWrapMode BSplineWrapMode Enumeration Enumeration of the possible ways of converting a "periodic" knot vector to an open knot vector. None (0) ==> no wrap possible OpenByAddintControlPoints (1) ==> wrapped by adding poles OpenByRemovingKnots (2) ==> wrapped by deleting extreme knots. Members Name Value Description None 0 No conversion to periodic OpenByAddingControlPoints 1 Convert to periodic by removing control points. This is typical for closed bcurve constructed by control points with maximum continuity.* Knots stay the same in open and periodic form.* Periodic form omits {degree} control points. OpenByRemovingKnots 2 Convert to periodic by adding special knots. This is typical of closed bcurve constructed as exact circular or elliptic arc* 2 knots on each end are omitted in open form* poles stay the same.
