CATSplineCurve

Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.

interface CATSplineCurve

Interface representing a curve interpolated between a set of points with a spline interpolation.

The CATSplineCurve is created by the CreateSplineCurve method of the CATGeoFactory interface and deleted with the Remove method. It is defined with:

CATMathSetOfPoints Points The definition points of the curve

The user can defined its own parameterization on the curve.
