Detailed Description

It calculates the distance between two curves with a close point; these distances can be maximum or minimum.

Constructor & Destructor Documentation

Extrema_LocateExtCC2d::Extrema_LocateExtCC2d	(	const Adaptor2d_Curve2d &	C1,
		const Adaptor2d_Curve2d &	C2,
		const Standard_Real	U0,
		const Standard_Real	V0
	)

Calculates the distance with a close point. The close point is defined by a parameter value on each curve. The function F(u,v)=distance(C1(u),C2(v)) has an extremun when gradient(f)=0. The algorithm searchs the zero near the close point.
