Constructor & Destructor Documentation

makVrv::DtVolumetricLighting::DtVolumetricLighting	(	DtDe &	de,
		const std::string &	postProcessType,
		bool	handles2D
	)

Constructor.

virtual makVrv::DtVolumetricLighting::~DtVolumetricLighting ( )

virtual

Destructor.

makVrv::DtVolumetricLighting::DtVolumetricLighting ( )

private

private default constructor. not allowed.

makVrv::DtVolumetricLighting::DtVolumetricLighting ( const DtVolumetricLighting & )

private

prevent copy-construction

Member Function Documentation

DtVolumetricLighting& makVrv::DtVolumetricLighting::operator= ( const DtVolumetricLighting & )

private

prevent assignment

virtual bool makVrv::DtVolumetricLighting::update ( DtChannel * channel )

virtual

Called once per frame from the DtPostProcessManager.

Implements makVrv::DtPostProcessor.

virtual void makVrv::DtVolumetricLighting::slot_reloadShaders ( )

virtual

slot for handling when the shaders are reloaded which recreates the Drawable

virtual void makVrv::DtVolumetricLighting::slot_setGodRayEffects ( bool enabled )

virtual

virtual osg::Texture* makVrv::DtVolumetricLighting::outputTexture ( )

virtual

get the output texture

Reimplemented from makVrv::DtPostProcessor.

virtual bool makVrv::DtVolumetricLighting::localEnabled ( )

virtual

is locally enabled?

virtual bool makVrv::DtVolumetricLighting::effectItrEnabled ( EffectMap::iterator & effect )

virtual

Is this effect (post processor sub-component) enabled?

virtual bool makVrv::DtVolumetricLighting::postProcessorEnabled ( ) const

virtual

Is this post processor enabled?

Reimplemented from makVrv::DtPostProcessor.

virtual void makVrv::DtVolumetricLighting::setInputTexture	(	const DtChannel *	channel,
		osg::Texture *	texture
	)

overridevirtual

Sets the image that is postprocessed; this may be the 3D scene rendered to a texture, or the output texture of a chained post processor. Managed by the DtPostProcessManager, you shouldn't need to call this yourself.

Reimplemented from makVrv::DtPostProcessor.

virtual bool makVrv::DtVolumetricLighting::needsOcclusionTexture ( ) const

overridevirtual

Volumetric lighting needs an occlusion texture when enabled.

Reimplemented from makVrv::DtPostProcessor.
