Extrema_GenLocateExtPS (const gp_Pnt &P, const Adaptor3d_Surface &S, const Standard_Real U0, const Standard_Real V0, const Standard_Real TolU, const Standard_Real TolV)
Calculates the distance with a close point. The close point is defined by the parameter values U0 and V0. The function F(u,v)=distance(S(u,v),p) has an extremun when gradient(F)=0. The algorithm searchs a zero near the close point. More...
