Detailed Description

A ParamLine2 is a line in space, with the following equations:

x = x0 + alpha*t y = y0 + beta*t

This class will replace the Line2 in coming versions.

Constructor & Destructor Documentation

ParamLine2() [1/3]

ParamLine2::ParamLine2	(	double	slope = 0,
		double	intcpt = 0 )

ParamLine2() [2/3]

ParamLine2::ParamLine2	(	const Coord &	,
		double	slope )

ParamLine2() [3/3]

ParamLine2::ParamLine2	(	const Coord &	p0,
		const Coord &	p1 )

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