DEFINE_STANDARD_ALLOC IntCurvesFace_Intersector (const TopoDS_Face &F, const Standard_Real aTol)
 Load a Face.

The Tolerance <Tol> is used to determine if the
first point of the segment is near the face. In
that case, the parameter of the intersection point
on the line can be a negative value (greater than -Tol).

void Perform (const gp_Lin &L, const Standard_Real PInf, const Standard_Real PSup)
 Perform the intersection between the
segment L and the loaded face.

PInf is the smallest parameter on the line
PSup is the highest parmaeter on the line

For an infinite line PInf and PSup can be
+/- RealLast.

void Perform (const Handle< Adaptor3d_HCurve > &HCu, const Standard_Real PInf, const Standard_Real PSup)
 same method for a HCurve from Adaptor3d.
PInf an PSup can also be - and + INF.

GeomAbs_SurfaceType SurfaceType () const
 Return the surface type

Standard_Boolean IsDone () const
 True is returned when the intersection have been computed.

Standard_Integer NbPnt () const
Standard_Real UParameter (const Standard_Integer I) const
 Returns the U parameter of the ith intersection point
on the surface.

Standard_Real VParameter (const Standard_Integer I) const
 Returns the V parameter of the ith intersection point
on the surface.

Standard_Real WParameter (const Standard_Integer I) const
 Returns the parameter of the ith intersection point
on the line.

const gp_PntPnt (const Standard_Integer I) const
 Returns the geometric point of the ith intersection
between the line and the surface.

IntCurveSurface_TransitionOnCurve Transition (const Standard_Integer I) const
 Returns the ith transition of the line on the surface.

TopAbs_State State (const Standard_Integer I) const
 Returns the ith state of the point on the face.
The values can be either TopAbs_IN
( the point is in the face)
or TopAbs_ON
( the point is on a boudary of the face).

const TopoDS_FaceFace () const
 Returns the significant face used to determine
the intersection.


TopAbs_State ClassifyUVPoint (const gp_Pnt2d &Puv) const
Bnd_Box Bounding () const
void Destroy ()
