Detailed Description

A Line2 is a line in the plane, with the following equations:

p(x,y) = p0 + dir * t

Though the line is infinitely long, one can treat the line as having a start when t=0 and a stop when t=1.

Constructor & Destructor Documentation

Line2::Line2 ( )

Normalizes so that t=0 is p0 and t=1 is p1

static Line2 Line2::fromPosAndDir	(	const Coord &	,
		const Coord &
	)

static

void Line2::getPerpendicularLine	(	Line2 &	,
		const Coord &	pt
	)		const

If checkinlimit is true, Coord::udf() will be returned if the intersection is ouside t=[0,1] on either line.
