void VolVis::Util::Camera::enablePerspective

(

bool

enable

)

Defines if the camera uses a perspective or an orthographic projection.

Parameters:

enable

if true, perspective projection is used, otherwise orthographic projection.

void VolVis::Util::Camera::setup	(	int	width,
		int	height
	)			const

Defines the OpenGL projection matrix according to the defined camera settings. The width and height for the viewport are defined by the parameters.

Parameters:

	width	width of viewport, only used in this method call. Doesn't affect the value defined with setViewport.
	height	height of viewport, only used in this method call. Doesn't affect the value defined with setViewport.

void VolVis::Util::Camera::setup

(

)

const

Defines the OpenGL projection matrix according to the defined camera settings. The width and height for the viewport are used as set with the method setZoom or in the constructor.

void VolVis::Util::Camera::setViewport	(	int	width,
		int	height
	)

Defines a new viewport which is used in the setup method without parameters.

Parameters:

	width	new width of viewport
	height	new height of viewport

void VolVis::Util::Camera::setZoom

(

double

zoom

)

Defines a zoom of the camera. A greater value than 1.0 means zoom in, a smaller value means zoom out.

Parameters:

zoom

new value for the camera zoom. This value has to be greater than zero
