Blend_FuncInv Class Reference

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.

DEFINE_STANDARD_ALLOC
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.
