Extrema_LocateExtCC2d (const Adaptor2d_Curve2d &C1, const Adaptor2d_Curve2d &C2, const Standard_Real U0, const Standard_Real V0)
Calculates the distance with a close point. The close point is defined by a parameter value on each curve. The function F(u,v)=distance(C1(u),C2(v)) has an extremun when gradient(f)=0. The algorithm searchs the zero near the close point. More...
