Detailed Description

An instance is a line defined by two Points. Lines are occasionally useful. For example, it is simple to display surface normals using this class. A Line is represented by the two Points which are its end-points.

Constructor & Destructor Documentation

cugl::Line::Line	(	const Point &	p,
		const Point &	q
	)

inline

Construct the Line from Point p to Point q.

Draw the line using glBegin(GL_LINE) ....

Friends And Related Function Documentation

Point meet	(	const Line &	k,
		const Plane &	p
	)

friend

Find the point where this line meets the plane p.

bool operator!=	(	const Line &	x,
		const Line &	y
	)

friend

Compare two lines. This function returns false only if corresponding components are exactly equal. Values that are theoretically equal but computed in different ways are likely to be unequal according to this function.

Definition at line 2701 of file cugl.h.

std::ostream& operator<<	(	std::ostream &	os,
		const Line &	k
	)

friend

Write a representation of the line to the output stream. The format is pt->pt where "\a pt" is the format used for points. If setw is used to set the width, it is passed to the inserter for Point.

bool operator==	(	const Line &	x,
		const Line &	y
	)

friend

Compare two lines. This function returns true only if corresponding components are exactly equal. Values that are theoretically equal but computed in different ways are likely to be unequal according to this function.
