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.

Members

Name Value Description
None No conversion performed.
OpenByAddingControlPoints The B-spline was opened up by adding degree wrap-around control points to the legacy periodic data.
* This is typical of B-splines constructed with maximum (degree - 1) continuity.
* Knots are unaffected by this conversion.
OpenByRemovingKnots The B-spline was opened up by removing degree extreme knots from the legacy periodic data.
* This is typical of rational B-spline curves representing full circles and ellipses.
* Poles are unaffected by this conversion.
