Deferred class for a function used to compute a blending
surface between two surfaces, using a guide line.
This function is used to find a solution on a restriction
of one of the surface.
The vector <X> used in Value, Values and Derivatives methods
has to be the vector of the parametric coordinates t,w,U,V
where t is the parameter on the curve on surface,
w is the parameter on the guide line,
U,V are the parametric coordinates of a point on the
partner surface.

Public Member Functions | |
Standard_Integer | NbVariables () const |
Returns 4. | |
virtual Standard_Integer | NbEquations () const =0 |
returns the number of equations of the function. | |
virtual Standard_Boolean | Value (const math_Vector &X, math_Vector &F)=0 |
computes the values <F> of the Functions for the variable <X>. Returns True if the computation was done successfully, False otherwise. | |
virtual Standard_Boolean | Derivatives (const math_Vector &X, math_Matrix &D)=0 |
returns the values <D> of the derivatives for the variable <X>. Returns True if the computation was done successfully, False otherwise. | |
virtual Standard_Boolean | Values (const math_Vector &X, math_Vector &F, math_Matrix &D)=0 |
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. | |
virtual void | Set (const Standard_Boolean OnFirst, const Handle< Adaptor2d_HCurve2d > &COnSurf)=0 |
Sets the CurveOnSurface on which a solution has to be found. If <OnFirst> is set to Standard_True, the curve will be on the first surface, otherwise the curve is on the second one. | |
virtual void | GetTolerance (math_Vector &Tolerance, const Standard_Real Tol) const =0 |
Returns in the vector Tolerance the parametric tolerance for each of the 4 variables; Tol is the tolerance used in 3d space. | |
virtual void | GetBounds (math_Vector &InfBound, math_Vector &SupBound) const =0 |
Returns in the vector InfBound the lowest values allowed for each of the 4 variables. Returns in the vector SupBound the greatest values allowed for each of the 4 variables. | |
virtual Standard_Boolean | IsSolution (const math_Vector &Sol, const Standard_Real Tol)=0 |
Returns Standard_True if Sol is a zero of the function. Tol is the tolerance used in 3d space. |
