virtual void makVrv::DtCloudDrawable::drawImplementation ( osg::RenderInfo & renderInfo ) const

virtual

Actually do the drawing.

virtual void makVrv::DtCloudDrawable::cleanupCloudLayer	(	SilverLining::Atmosphere *	atmosphere,
		unsigned int	layerHandle
	)		const

virtual

Used to cleanup any SilverLining::CloudLayer specific state that the drawable has. currently only removes the entry in the default altitude map.

virtual void makVrv::DtCloudDrawable::fadeCloudsWithAltitude	(	const Vector3_64 &	cameraPosition,
		SilverLining::CloudLayer *	layer,
		SilverLining::ThreadCameraStreamData *	tcsData,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

fade clouds depending on the altitude, for a given layer

virtual void makVrv::DtCloudDrawable::fadeCloudsWithAltitude	(	const Vector3_64 &	cameraPosition,
		SilverLining::Atmosphere *	atmosphere,
		SilverLining::ThreadCameraStreamData *	tcsData,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

fade clouds depending on the altitude for all layers; calls the method above for each layer

virtual void makVrv::DtCloudDrawable::updateCloudAltitudes	(	const Vector3_64 &	cameraPosition,
		SilverLining::Atmosphere *	atmosphere,
		SilverLining::ThreadCameraStreamData *	tcsData,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

update cloud altitudes

virtual bool makVrv::DtCloudDrawable::updateShader	(	osg::Node *	node,
		osg::State &	state,
		SilverLining::Atmosphere *	atmosphere,
		SilverLining::ThreadCameraStreamData *	tcsData,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

virtual void makVrv::DtCloudDrawable::updateOpenGLState	(	osg::State &	state,
		SilverLining::Atmosphere *	atmosphere,
		osg::Camera *	osgCamera,
		SilverLining::ThreadCameraStreamData *	tcsData,

		SilverLining::Atmosphere *	atm,
		bool	isReflection,
		SilverLining::ThreadCameraStreamData *	tcsData
	)		const

protectedvirtual

virtual void makVrv::DtCloudDrawable::slot_environmentChanged ( const std::string & name )

protectedvirtual

Slot when the environment is changed, for example, change from cloudy to snowy.

Parameters

name	The new name of the environment

virtual bool makVrv::DtCloudDrawable::computeHeightAboveTerrain	(	const Vector3_64 &	localPosition,
		double &	heightOfGround,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

compute height above terrain

virtual void makVrv::DtCloudDrawable::updateCloudLayerAltitudes	(	SilverLining::Atmosphere *	atmosphere,
		SilverLining::ThreadCameraStreamData *	tcsData,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

update cloud layer altitude

virtual void makVrv::DtCloudDrawable::updateCubeMap	(	SilverLining::Atmosphere *	atmosphere,
		SilverLining::ThreadCameraStreamData *	tcsData,
		const osg::Camera *	osgCamera,
		const Vector3_64 &	cameraPosition,
		osg::State &	state,
		DtSilverLiningGroupTcsUserData *	userData
	)		const

protectedvirtual

update cube map

virtual bool makVrv::DtCloudDrawable::updateDepthTextureIfNecessary ( osg::RenderInfo & renderInfo ) const

protectedvirtual

Copy the depth buffer from the currently bound frame buffer to a texture that the clouds can use for smoothing clouds near other objects. Returns true if the depth texture was actually updated and bound.

virtual bool makVrv::DtCloudDrawable::anyLayerNeedsDepthTexture ( void ) const

protectedvirtual

Whether any cloud layer needs the depth texture (e.g. stratocumulus always needs it)

virtual void makVrv::DtCloudDrawable::unbindDepthTexture ( osg::RenderInfo & renderInfo ) const

protectedvirtual

After the drawable is done with the depth texture we need to unbind it so SLI is fast.
