GeometricObjects Interface CATPSpline
Usage: an implementation of this interface is supplied and you must use it as is. You should not reimplement it.
interface CATPSpline
Interface representing a curve interpolated between a set of points on surface
with a spline interpolation .
The CATPSpline is created by the CreatePSpline
method of the CATGeoFactory interface and deleted with the Remove method.
It is defined with:
| CATMathSetOfPoints | Points |
The set of points on surface defining the curve |
| CATSurface | iSupport |
The surface on which the Spline is defined |
The user may define its own parameterization on the curve.
