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.

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. |
