 Extrema_GenExtCS (const Adaptor3d_Curve &C, const Adaptor3d_Surface &S, const Standard_Integer NbT, const Standard_Integer NbU, const Standard_Integer NbV, const Standard_Real Tol1, const Standard_Real Tol2)
 It calculates all the distances.
The function F(u,v)=distance(S1(u1,v1),S2(u2,v2)) has an
extremum when gradient(F)=0. The algorithm searchs
all the zeros inside the definition ranges of the
surfaces.
NbU and NbV are used to locate the close points on the
surface and NbT on the curve to find the zeros.

 It calculates all the distances.
The function F(u,v)=distance(P,S(u,v)) has an
extremum when gradient(F)=0. The algorithm searchs
all the zeros inside the definition ranges of the
surface.
NbT,NbU and NbV are used to locate the close points
to find the zeros.
