TopClass_Intersection3d Class Reference

Template class for the intersection algorithm required
by the 3D classifications.

(a intersection point near the origin of the line, ie.
at a distance less or equal than <tolerance>, will be
returned even if it has a negative parameter.)

#include <TopClass_Intersection3d.hxx>

virtual DEFINE_STANDARD_ALLOC void Perform (const gp_Lin &L, const Standard_Real Prm, const Standard_Real Tol, const TopoDS_Face &Face)=0
 Perform the intersection between the
segment L(0) ... L(Prm) and the Face <Face>.

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).

virtual Standard_Boolean IsDone () const =0
 True is returned when the intersection have been computed.

virtual Standard_Boolean HasAPoint () const =0
 True is returned if a point has been found.

virtual const
IntCurveSurface_IntersectionPoint
Point () const =0
 Returns the Intersection Point.


virtual TopAbs_State State () const =0
 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).
