HLRBRep_TheLocateExtPCOfTheProjPCurOfCInter (const gp_Pnt2d &P, const Standard_Address &C, const Standard_Real U0, const Standard_Real TolU)
Calculates the distance with a close point. The close point is defined by the parameter value U0. The function F(u)=distance(P,C(u)) has an extremum when g(u)=dF/du=0. The algorithm searchs a zero near the close point. TolU is used to decide to stop the iterations. At the nth iteration, the criteria is: abs(Un - Un-1) < TolU. More...
