Member Function Documentation

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

virtual

Add a node to the specified SceneRoot.

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

virtual

Remove a node from the specified SceneRoot.

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

virtual

Traverse from the specified SceneRoot with the given visitor.

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

virtual

Set the nodemask of a SceneRoot.

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

virtual

Get the nodemask of a SceneRoot.

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

protectedvirtual

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