Detailed Description

Stores the current view volume.

This element stores the current view volume.

Warning:: Open Inventor does not guarantee that the view volume element corresponds to the current view and projection matrix elements used for rendering. A node could, for example, set the SoProjectionMatrixElement but not the SoViewVolumeElement. An example of this is the SoDepthOffset node. If you need these matrices, it is safer to access them through the SoViewingMatrixElement and SoProjectionMatrixElement. Cameras nodes do set the view volume and both matrix elements on a render traversal.

static const SbViewVolume& SoViewVolumeElement::get ( SoState * state ) [static]

Returns the current view volume from the state.

static int SoViewVolumeElement::getClassStackIndex ( ) [static]

Returns the stack id for this element.

Reimplemented from SoReplacedElement.

static SoType SoViewVolumeElement::getClassTypeId ( ) [static]

Returns the type identifier for this class.

Reimplemented from SoReplacedElement.

static SbBool SoViewVolumeElement::isSet ( SoState * state ) [static]

Returns TRUE if the view volume has been set in the state.

virtual void SoViewVolumeElement::print ( FILE * fp ) const [virtual]

Prints element (for debugging).

Reimplemented from SoReplacedElement.

static void SoViewVolumeElement::set	(	SoState *	state,
		SoNode *	node,
		const SbViewVolume &	viewVolume
	)			`[static]`

Sets the view volume in the state.
