Public Member Functions
	CGFcamera ()
	Base constructor.
virtual	~CGFcamera ()
	Base destructor.
virtual void	applyView ()
	Applies View transformation (typically used in the beginning of a scene render, in CGFscene::display() )
virtual void	updateProjectionMatrix (int width, int height)
	Updates the projection matrix. Typically invoked after viewport change, e.g. as a result of a window reshape that triggers CGFapplication::reshape()
virtual void	setExamineMode ()
	Sets the camera to move in Examine mode i.e., to rotate around a fixed point in front of it.
virtual void	setWalkMode ()
	Sets the camera to move in Walk mode i.e., to rotate around itself.
virtual void	setX (float value)
	Sets camera X coordinate.
virtual void	setY (float value)
	Sets camera Y coordinate.
virtual void	setZ (float value)
	Sets camera Z coordinate.
Utility functions for relative/incremental camera movement
virtual bool	rotateTo (int axis, float angle, float increment=0.5f)
	Rotates the camera around axis by increment degrees, unless it has reached angle degrees. Useful for stepping a rotation in an animation.
virtual bool	rotate (int axis, float angle)
	Rotates the camera around axis by angle degrees.
virtual bool	setRotation (int axis, float angle)
	Sets the rotation around axis to be angle degrees.
virtual bool	moveTo (int axis, float value, float increment=0.5f)
	Moves the camera along axis by increment units, unless value has been reached.
virtual bool	translate (int axis, float value)
	Moves the camera along axis by value units.
