Detailed Description

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.)

Constructor & Destructor Documentation

TopClass_Intersection3d::TopClass_Intersection3d ( )

protected

Empty constructor.

Member Function Documentation

virtual Standard_Boolean TopClass_Intersection3d::HasAPoint ( ) const

pure virtual

True is returned if a point has been found.

virtual Standard_Boolean TopClass_Intersection3d::IsDone ( ) const

pure virtual

True is returned when the intersection have been computed.

virtual void TopClass_Intersection3d::Perform ( const gp_Lin &  L, const Standard_Real  Prm, const Standard_Real  Tol, const TopoDS_Face &  Face  )

pure virtual

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 const IntCurveSurface_IntersectionPoint& TopClass_Intersection3d::Point ( ) const

pure virtual

Returns the Intersection Point.

virtual TopAbs_State TopClass_Intersection3d::State ( ) const

pure virtual

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).
