Output Ports: Result

Control Points	Array of control point positions. At least 4 positions are needed to define a B-spline segment.
t	The parameter value for which to return the corresponding position on the curve.
Coincident End Knots	Repeats the first and last control point positions so that the curve passes through the end points.
