Public Attributes
float	ScreenDistance
	The parameter screen_distance tells how far from the eye of the observer is the screen, and it influences the so-called «aperture» (the field-of-view angle along the horizontal direction).
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 class implements an observer seeing the world through a perspective projection.

FireRay()

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

Shoot a ray through the camera's screen

Parameters

u	x-axis
