None* 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. :param P: :type P: gp_Pnt2d :param C: :type C: Adaptor2d_Curve2d & :param U0: :type U0: float :param TolU: :type TolU: float :rtype: None* Calculates the distance with a close point.

static FindParameter()

• Returns the parameter V of the point on the parametric curve corresponding to the Point Pnt. The Correspondance between Pnt and the point P(V) on the parametric curve must be coherent with the way of determination of the signed distance between a point and the implicit curve. Tol is the tolerance on the distance between a point and the parametrised curve. In that case, no bounds are given. The research of the rigth parameter has to be made on the natural parametric domain of the curve.

  float* Returns the parameter V of the point on the parametric curve corresponding to the Point Pnt. The Correspondance between Pnt and the point P(V) on the parametric curve must be coherent with the way of determination of the signed distance between a point and the implicit curve. Tol is the tolerance on the distance between a point and the parametrised curve. LowParameter and HighParameter give the boundaries of the interval in wich the parameter certainly lies. These parameters are given to implement a more efficient algoritm. So, it is not necessary to check that the returned value verifies LowParameter <= Value <= HighParameter.
