Public Attributes
float	AspectRatio
	The parameter aspect_ratio defines how larger than the height is the image. For fullscreen images, you should probably set aspect_ratio to 16/9, as this is the most used aspect ratio used in modern monitors.
Transformation	Transf

Detailed Description

This struct implements an observer seeing the world through an orthogonal projection.

FireRay()

Ray PGENLib.OrthogonalCamera.FireRay	(	float	u,
		float	v
	)

Shoot a ray through the camera's screen

Parameters

u	x-axis
v	y-axis

Returns

The coordinates (u, v) specify the point on the screen where the ray crosses it. The following diagram represents the coordinates (0,0); (1,0); (0,1); (1,1): (0, 1) (1, 1) +---------------------------—+
