Parameters

Count

Size of KnotPoints array

KnotPoints

• in-process, unmanaged C++: Pointer to an array of double values between 0 and 1, inclusive

Return Value

Before calling this method, call ISplineParamData::KnotPointsCount to populate the Count parameter.

Together with control points, knots determine the shape and smoothness of a spline. The knot vector divides the parametric space into intervals or knot spans. These intervals may be uniform or non-uniform. Each interval governs a different control point.
