ConfusionTolerance()

Standard_Real Geom2dHatch_Intersector::ConfusionTolerance

(

)

const

Returns the confusion tolerance of the intersector.

Intersect()

void Geom2dHatch_Intersector::Intersect	(	const Geom2dAdaptor_Curve &	C1,
		const Geom2dAdaptor_Curve &	C2
	)

Intersects the curves C1 and C2. The results are retreived by the usual methods described in IntRes2d_Intersection. Creates an intersector.

LocalGeometry()

void Geom2dHatch_Intersector::LocalGeometry	(	const Geom2dAdaptor_Curve &	E,
		const Standard_Real	U,
		gp_Dir2d &	T,
		gp_Dir2d &	N,
		Standard_Real &	C
	)		const

Returns in <T>, <N> and the tangent, normal and curvature of the edge <E> at parameter value <U>.

Perform()

void Geom2dHatch_Intersector::Perform	(	const gp_Lin2d &	L,
		const Standard_Real	P,
		const Standard_Real	Tol,
		const Geom2dAdaptor_Curve &	E
	)

Performs the intersection between the 2d line segment (<L>,.

) and the Curve <E>. The line segment is the part of the 2d line <L> of parameter range [0,
