Detailed Description

Class that represents a camera on the scene.

Constructor & Destructor Documentation

OCamera::OCamera	(	float	fieldOfViewDeg = 45.0f,
		float	aspectRatio = 4.0f/3,
		float	zNear = 1.0f,
		float	zFar = 5.0f,
		const OVector3 &	pos = OVector3(0, 0, -1),
		const OVector3 &	dir = OVector3(0, 0, 1)
	)

Class constructor.

The constructor takes in all the attributes of the scene camera.

Parameters

fieldOfViewDeg	Angle of the camera's field of view in degrees.
aspectRatio	The aspect ration of the screen (width/height).
zNear	Nearest camera depth.
zFar	Farthest camera depth.
pos	Camera position.
dir	Camera direction vector.
