DEFINE_STANDARD_ALLOC BRepClass3d_Intersector3d ()
 Empty constructor.

void Perform (const gp_Lin &L, const Standard_Real Prm, const Standard_Real Tol, const TopoDS_Face &F)
 Perform the intersection between the
segment L(0) ... L(Prm) and the Shape <Sh>.

Only the point with the smallest parameter on the
line is returned.

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).

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

Standard_Boolean HasAPoint () const
 True is returned if a point has been found.

Standard_Real UParameter () const
 Returns the U parameter of the intersection point
on the surface.

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

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

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

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

TopAbs_State State () const
 Returns the 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.
