 GeomFill_EvolvedSection (const Handle< Geom_Curve > &C, const Handle< Law_Function > &L)
 Make an SectionLaw with a Curve and a real Law.

virtual Standard_Boolean D0 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColStd_Array1OfReal &Weigths)
 compute the section for v = param

virtual Standard_Boolean D1 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColgp_Array1OfVec &DPoles, TColStd_Array1OfReal &Weigths, TColStd_Array1OfReal &DWeigths)
 compute the first derivative in v direction of the
section for v = param
Warning : It used only for C1 or C2 aproximation

virtual Standard_Boolean D2 (const Standard_Real Param, TColgp_Array1OfPnt &Poles, TColgp_Array1OfVec &DPoles, TColgp_Array1OfVec &D2Poles, TColStd_Array1OfReal &Weigths, TColStd_Array1OfReal &DWeigths, TColStd_Array1OfReal &D2Weigths)
 compute the second derivative in v direction of the
section for v = param
Warning : It used only for C2 aproximation

virtual Handle_Geom_BSplineSurface BSplineSurface () const
 give if possible an bspline Surface, like iso-v are the
section. If it is not possible this methode have to
get an Null Surface. Is it the default implementation.

virtual void SectionShape (Standard_Integer &NbPoles, Standard_Integer &NbKnots, Standard_Integer &Degree) const
 get the format of an section

virtual void Knots (TColStd_Array1OfReal &TKnots) const
 get the Knots of the section

virtual void Mults (TColStd_Array1OfInteger &TMults) const
 get the Multplicities of the section

virtual Standard_Boolean IsRational () const
 Returns if the sections are rationnal or not

virtual Standard_Boolean IsUPeriodic () const
 Returns if the sections are periodic or not

virtual Standard_Boolean IsVPeriodic () const
 Returns if the law isperiodic or not

virtual Standard_Integer NbIntervals (const GeomAbs_Shape S) const
 Returns the number of intervals for continuity
<S>.
May be one if Continuity(me) >= <S>

virtual void Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) const
 Stores in <T> the parameters bounding the intervals
of continuity <S>.

The array must provide enough room to accomodate
for the parameters. i.e. T.Length() > NbIntervals()

virtual void SetInterval (const Standard_Real First, const Standard_Real Last)
 Sets the bounds of the parametric interval on
the function
This determines the derivatives in these values if the
function is not Cn.

virtual void GetInterval (Standard_Real &First, Standard_Real &Last) const
 Gets the bounds of the parametric interval on
the function

virtual void GetDomain (Standard_Real &First, Standard_Real &Last) const
 Gets the bounds of the function parametric domain.
Warning: This domain it is not modified by the
SetValue method

virtual void GetTolerance (const Standard_Real BoundTol, const Standard_Real SurfTol, const Standard_Real AngleTol, TColStd_Array1OfReal &Tol3d) const
 Returns the tolerances associated at each poles to
reach in approximation, to satisfy: BoundTol error
at the Boundary AngleTol tangent error at the
Boundary (in radian) SurfTol error inside the
surface.

virtual gp_Pnt BarycentreOfSurf () const
 Get the barycentre of Surface.
An very poor estimation is sufficent.
This information is usefull to perform well
conditioned rational approximation.
Warning: Used only if <me> IsRational

virtual Standard_Real MaximalSection () const
 Returns the length of the greater section. This
information is usefull to G1's control.
Warning: With an little value, approximation can be slower.

virtual void GetMinimalWeight (TColStd_Array1OfReal &Weigths) const
 Compute the minimal value of weight for each poles
in all sections.
This information is usefull to control error
in rational approximation.
Warning: Used only if <me> IsRational

virtual Standard_Boolean IsConstant (Standard_Real &Error) const
 return True If the Law isConstant

virtual Handle_Geom_Curve ConstantSection () const
 Return the constant Section if <me> IsConstant.
