Detailed Description

A Transportation Link a series of points, connecting one node to another.

Member Function Documentation

double TLink::DistanceToPoint	(	const DPoint2 &	point,
		bool	bAllowEnds = `true`
	)

Find closest lateral distance from a given point to the link.

double TLink::GetLinearCoordinates	(	const DPoint2 &	p,
		double &	result_a,
		double &	result_b,
		DPoint2 &	closest,
		int &	linkpoint,
		float &	fractional,
		bool	bAllowEnds = `true`
	)

Produces the "linear coordinates" a and b, where a is the distance along the link, and b is the signed lateral distance orthogonal to the link at that point.

Parameters

p	The input point.
result_a	The resulting distance along the link.
result_b	The signed lateral (or absolute) distance to the link.
closest	The closest point on the link.
linkpoint	Index into the links points just before the closest point.
fractional	Fractional distance between this link point and the next.
bAllowEnds	If true, then for cases where the the closest point is either end of the link, the distance to that point is returned. Otherwise, only laterial distances are returned.
