virtual
Handle_GeomFill_TrihedronLaw 
Copy () const
virtual void SetCurve (const Handle< Adaptor3d_HCurve > &C)
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 Standard_Boolean D0 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &Normal, gp_Vec &BiNormal)
 compute Triedrhon on curve at parameter

virtual Standard_Boolean D1 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &DTangent, gp_Vec &Normal, gp_Vec &DNormal, gp_Vec &BiNormal, gp_Vec &DBiNormal)
 compute Triedrhon and derivative Trihedron on curve
at parameter
Warning : It used only for C1 or C2 aproximation

virtual Standard_Boolean D2 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &DTangent, gp_Vec &D2Tangent, gp_Vec &Normal, gp_Vec &DNormal, gp_Vec &D2Normal, gp_Vec &BiNormal, gp_Vec &DBiNormal, gp_Vec &D2BiNormal)
 compute Trihedron on curve
first and seconde derivatives.
Warning : It used only for C2 aproximation

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 GetAverageLaw (gp_Vec &ATangent, gp_Vec &ANormal, gp_Vec &ABiNormal)
 Get average value of Tangent(t) and Normal(t) it is usfull to
make fast approximation of rational surfaces.

virtual Standard_Boolean IsConstant () const
 Say if the law is Constant.

virtual Standard_Boolean IsOnlyBy3dCurve () const
 Return True.
