Member Function Documentation

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

virtual

Add a node to the specified SceneRoot.

virtual void makVrv::DtSceneGraph::addRootToNode ( osg::Group *  node, const DtOsgRenderer::SceneRoot &  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 DtOsgRenderer::SceneRoot &  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 void makVrv::DtSceneGraph::removeNodeFromRoot ( osg::Node *  node, const DtOsgRenderer::SceneRoot &  sr  )

virtual

Remove a node from the specified SceneRoot.

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

virtual

Traverse from the specified SceneRoot with the given visitor.

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

virtual

Set the nodemask of a SceneRoot.

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

virtual

Get the nodemask of a SceneRoot.

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

virtual

Get the bounding sphere of sceneRoot.

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

virtual

Get the bounding sphere of list of sceneRoots.

virtual osg::Group* makVrv::DtSceneGraph::findSceneRootChildByName ( const DtOsgRenderer::SceneRoot &  parent, const std::string &  rootName  )

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)

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 ( int  modelSet )

virtual

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

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

virtual

Test if this group matches the given scene root.

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

protectedvirtual

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