GeomFill_CurveAndTrihedron Class Reference

Define location law with an TrihedronLaw and an
curve
Definition Location is :
transformed section coordinates in (Curve(v)),
(Normal(v), BiNormal(v), Tangente(v))) systeme are
the same like section shape coordinates in
(O,(OX, OY, OZ)) systeme.

 compute location 2d points and associated
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 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 Standard_Real GetMaximalNorm ()
 Get the maximum Norm of the matrix-location part. It
is usful to find an good Tolerance to approx M(t).

virtual void GetAverageLaw (gp_Mat &AM, gp_Vec &AV)
 Get average value of M(t) and V(t) it is usfull to
make fast approximation of rational surfaces.

virtual Standard_Boolean IsTranslation (Standard_Real &Error) const
 Say if the Location Law, is an translation of Location
The default implementation is " returns False ".

virtual Standard_Boolean IsRotation (Standard_Real &Error) const
 Say if the Location Law, is a rotation of Location
The default implementation is " returns False ".
