virtual Standard_EXPORT Handle_GeomFill_TrihedronLaw Copy () const
virtual Standard_EXPORT Standard_Boolean D0 (const Standard_Real Param, gp_Vec &Tangent, gp_Vec &Normal, gp_Vec &BiNormal)
 compute Triedrhon on curve at parameter <param>

virtual Standard_EXPORT 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 <param>
Warning : It used only for C1 or C2 aproximation

virtual Standard_EXPORT 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_EXPORT Standard_Integer NbIntervals (const GeomAbs_Shape S) const
 Returns the number of intervals for continuity
<s>.
May be one if Continuity(me) >= <s>
.
virtual Standard_EXPORT 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 Standard_EXPORT 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_EXPORT Standard_Boolean IsConstant () const
 Return True.
