Root class for 3D curves manipulated by handles, on
which geometric algorithms work.
An adapted curve is an interface between the
services provided by a curve and those required of
the curve by algorithms which use it.
Two derived concrete classes are provided:

virtual const Adaptor3d_Curve & | Curve () const =0 |
| Returns a pointer to the Curve inside the HCurve.

virtual Adaptor3d_Curve & | GetCurve ()=0 |
| Returns a pointer to the Curve inside the HCurve.

GeomAbs_Shape | Continuity () const |
Standard_Integer | NbIntervals (const GeomAbs_Shape S) |
void | Intervals (TColStd_Array1OfReal &T, const GeomAbs_Shape S) |
| 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()

Handle_Adaptor3d_HCurve | Trim (const Standard_Real First, const Standard_Real Last, const Standard_Real Tol) const |
| Returns a curve equivalent of <me> between
parameters <First> and <Last>. <Tol> is used to
test for 3d points confusion.
//! If <First> >= <Last>
