DEFINE_STANDARD_ALLOC Extrema_ExtCS ()
 Extrema_ExtCS (const Adaptor3d_Curve &C, const Adaptor3d_Surface &S, const Standard_Real TolC, const Standard_Real TolS)
 It calculates all the distances between C and S.

 Extrema_ExtCS (const Adaptor3d_Curve &C, const Adaptor3d_Surface &S, const Standard_Real UCinf, const Standard_Real UCsup, const Standard_Real Uinf, const Standard_Real Usup, const Standard_Real Vinf, const Standard_Real Vsup, const Standard_Real TolC, const Standard_Real TolS)
 It calculates all the distances between C and S.
UCinf and UCmax are the start and end parameters
of the curve.

void Initialize (const Adaptor3d_Surface &S, const Standard_Real Uinf, const Standard_Real Usup, const Standard_Real Vinf, const Standard_Real Vsup, const Standard_Real TolC, const Standard_Real TolS)
 Initializes the fields of the algorithm.

void Perform (const Adaptor3d_Curve &C, const Standard_Real Uinf, const Standard_Real Usup)
 Computes the distances.
An exception is raised if the fieds have not been
initialized.

Standard_Boolean IsDone () const
 Returns True if the distances are found.

Standard_Boolean IsParallel () const
 Returns True if the curve is on a parallel surface.

Standard_Integer NbExt () const
 Returns the number of extremum distances.

Standard_Real SquareDistance (const Standard_Integer N) const
 Returns the value of the Nth resulting square distance.

void Points (const Standard_Integer N, Extrema_POnCurv &P1, Extrema_POnSurf &P2) const
 Returns the point of the Nth resulting distance.
