Detailed Description

An infinite ray, with a specific origin and direction.

It begins at its origin and continues in one direction to infinity, and it has no radius. Useful for picking from a window, or for gravity effects.

CollisionRay

(

)

Creates an invalid ray.

This isn't terribly useful; it's expected that the user will subsequently adjust the ray via set_origin()/set_direction() or set_from_lens().

bool setFromLens	(	LensNode	camera,
		float	px,
		float	py
	)

Accepts a LensNode and a 2-d point in the range [-1,1].

Sets the CollisionRay so that it begins at the LensNode's near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

bool setFromLens	(	LensNode	camera,
		Point2 const	point
	)

Accepts a LensNode and a 2-d point in the range [-1,1].

Sets the CollisionRay so that it begins at the LensNode's near plane and extends to infinity, making it suitable for picking objects from the screen given a camera and a mouse location.

Returns true if the point was acceptable, false otherwise.
