Detailed Description

Definition of the domain of parameter on a 2d-curve. Most of the time, a domain is defined by two extremities. An extremity is made of :

a point in 2d-space (Pnt2d from gp),
a parameter on the curve,
a tolerance in the 2d-space. Sometimes, it can be made of 0 or 1 point ( for an infinite or semi-infinite line for example).

For Intersection algorithms, Ellipses and Circles Domains must be closed. So, SetEquivalentParameters(.,.) method must be called after initializing the first and the last bounds.

Constructor & Destructor Documentation

IntRes2d_Domain::IntRes2d_Domain ( )

Creates an infinite Domain (HasFirstPoint = False and HasLastPoint = False).

IntRes2d_Domain::IntRes2d_Domain	(	const gp_Pnt2d &	Pnt1,
		const Standard_Real	Par1,
		const Standard_Real	Tol1,
		const gp_Pnt2d &	Pnt2,
		const Standard_Real	Par2,
		const Standard_Real	Tol2
	)

Creates a bounded Domain.

IntRes2d_Domain::IntRes2d_Domain	(	const gp_Pnt2d &	Pnt,
		const Standard_Real	Par,
		const Standard_Real	Tol,
		const Standard_Boolean	First
	)

Creates a semi-infinite Domain. If First is set to True, the given point is the first point of the domain, otherwise it is the last point.
