class SurfPointEvolRadInv from BRepBlend
inherits SurfPointFuncInv from Blend
---Purpose: This function is used to find a solution on a done
-- point of the curve when using SurfRstConsRad or
-- CSConstRad...
-- The vector <X> used in Value, Values and Derivatives
-- methods has to be the vector of the parametric
-- coordinates w, U, V where w is the parameter on the
-- guide line, U,V are the parametric coordinates of a
-- point on the partner surface.

NbEquations(me)
---Purpose: returns 3.
returns Integer from Standard;
Value(me: in out; X: Vector; F: out Vector)
---Purpose: computes the values <F> of the Functions for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean from Standard;
Derivatives(me: in out; X: Vector; D: out Matrix)
---Purpose: returns the values <D> of the derivatives for the
-- variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean from Standard;
Values(me: in out; X: Vector; F: out Vector; D: out Matrix)
---Purpose: returns the values <F> of the functions and the derivatives
-- <D> for the variable <X>.
-- Returns True if the computation was done successfully,
-- False otherwise.
returns Boolean from Standard;
Set(me: in out; P : Pnt from gp);
---Purpose: Set the Point on which a solution has to be found.
GetTolerance(me; Tolerance: out Vector from math; Tol: Real from Standard);
---Purpose: Returns in the vector Tolerance the parametric tolerance
-- for each of the 3 variables;
-- Tol is the tolerance used in 3d space.
GetBounds(me; InfBound,SupBound: out Vector from math);
---Purpose: Returns in the vector InfBound the lowest values allowed
-- for each of the 3 variables.
-- Returns in the vector SupBound the greatest values allowed
-- for each of the 3 variables.
IsSolution(me: in out; Sol: Vector from math; Tol: Real from Standard)
---Purpose: Returns Standard_True if Sol is a zero of the function.
-- Tol is the tolerance used in 3d space.
returns Boolean from Standard;
