virtual bool makVrv::DtSceneGraph::isSceneRootEmpty ( const DtSceneRoot & sr )

virtual

Checks to see if the specified sceneRoot currently has any children. Note that: in some cases, this may cause a scene root to be created if it doesn't exist A scene root that doesn't exist (and doesn't get created) is considered 'empty' by this method.

virtual void makVrv::DtSceneGraph::addNodeToRoot	(	osg::Node *	node,
		const DtSceneRoot &	sr,
		bool	createOnAccess
	)

virtual

Add a node to the specified SceneRoot.

virtual void makVrv::DtSceneGraph::addSceneRootToRoot	(	const DtSceneRoot &	childRoot,
		const DtSceneRoot &	parentRoot,
		bool	createOnAccess
	)

virtual

Add a (child) SceneRoot to the specified SceneRoot.

virtual void makVrv::DtSceneGraph::addRootToNode	(	osg::Group *	node,
		const DtSceneRoot &	sr,
		bool	createOnAccess
	)

virtual

Add the specified SceneRoot to an OSG group node.

This should be used with caution - it creates a dependency between the caller and the scene graph's internal node structure.

virtual void makVrv::DtSceneGraph::addActiveRootToNode	(	osg::Group *	node,
		const DtSceneRoot &	sr,
		bool	createOnAccess
	)

virtual

Add the specified SceneRoot to an OSG group node using its active parent.

This should be used with caution - it creates a dependency between the caller and the scene graph's internal node structure.

virtual bool makVrv::DtSceneGraph::removeNodeFromRoot	(	osg::Node *	node,
		const DtSceneRoot &	sr
	)

virtual

Remove a node from the specified SceneRoot.

virtual void makVrv::DtSceneGraph::removeSceneRootFromRoot	(	const DtSceneRoot &	childRoot,
		const DtSceneRoot &	parentRoot
	)

virtual

Remove a (child) sceneRoot from the specified parent SceneRoot.

virtual void makVrv::DtSceneGraph::removeRootFromNode	(	osg::Group *	node,
		const DtSceneRoot &	sr
	)

virtual

Remove a scene root from an OSG group node.

This should be used with caution - it creates a dependency between the caller and the scene graph's internal node structure.

virtual void makVrv::DtSceneGraph::removeActiveRootFromNode	(	osg::Group *	node,
		const DtSceneRoot &	sr
	)

virtual

Remove a scene root's active parent from an OSG group node.

This should be used with caution - it creates a dependency between the caller and the scene graph's internal node structure.

virtual void makVrv::DtSceneGraph::traverseRoot	(	osg::NodeVisitor &	nv,
		const DtSceneRoot &	sr
	)

virtual

Traverse from the specified SceneRoot with the given visitor.

virtual void makVrv::DtSceneGraph::setSceneRootNodeMask	(	const DtSceneRoot &	sr,
		osg::Node::NodeMask	nodeMask
	)

virtual

Set the nodemask of a SceneRoot.

virtual osg::Node::NodeMask makVrv::DtSceneGraph::sceneRootNodeMask ( const DtSceneRoot & sr )

virtual

Get the nodemask of a SceneRoot.

virtual osg::BoundingSphere makVrv::DtSceneGraph::sceneRootBound ( const DtSceneRoot & sr )

virtual

Get the bounding sphere of sceneRoot.

virtual osg::BoundingSphere makVrv::DtSceneGraph::sceneRootListBound ( const DtSceneRootList & srList )

virtual

Get the bounding sphere of list of sceneRoots.

virtual osg::Group* makVrv::DtSceneGraph::findSceneRootChildByName	(	const DtSceneRoot &	parent,
		const std::string &	rootName,
		bool	subString = `false`
	)

virtual

Look up a root by name in the parent specified by SceneRoot.

This should not be used to access roots that are created by Vantage. It Is provided for plugins to find the roots possibly created by other plugins (such as multiple GlStudio plugins, for example)

Parameters

subString,: matches name as a substring of the name, else exact name match

virtual void makVrv::DtSceneGraph::setRenderRootAsSceneData ( osgViewer::View & view )

virtual

Set the sceneData of a view to the top of the scene graph.

virtual osg::Group* makVrv::DtSceneGraph::createModelSetRoot ( DtModelSetId modelSet )

virtual

Create a root node for the model set and return it.

virtual bool makVrv::DtSceneGraph::matchesSceneRoot	(	const DtSceneRoot &	sr,
		osg::Group *	group
	)

virtual

Test if this group matches the given scene root.

virtual osg::Group* makVrv::DtSceneGraph::getContainerRoot	(	const DtSceneRoot &	root,
		bool	createOnAccess
	)

virtual osg::Group* makVrv::DtSceneGraph::getActiveRoot ( const DtSceneRoot & root )
