BSplineWrapMode Enumeration
B-spline curve and surface types in this library are non-periodic. But they can be created from legacy periodic data.
This enumeration lists the possible ways a B-spline object can have been created from legacy periodic data.

No conversion performed. |
| OpenByAddingControlPoints |
|
The legacy periodic B-spline data was opened up by adding degree wrap-around poles.
* This is typical of B-spline curves and surfaces constructed with maximum degree - 1 continuity.
* Knots are unaffected by this conversion. |
| OpenByRemovingKnots |
|
The legacy periodic B-spline data was opened up by removing degree exterior knots.
* This is typical of rational B-spline curves representing full circles and ellipses.
* Poles are unaffected by this conversion. |
