Detailed Description
Scene Graph Node with Canvas-Dependent Switch.Constructor & Destructor Documentation
| VRS::SceneSwitch::SceneSwitch | ( | ) |
An SceneSwitch node groups scene subgraphs and assigns each subgraph to a specific canvas. Based on the canvas whose engine evaluates the scene graph, only those scene subgraphs are selected which are assigned to the canvas. This allows for specifying canvas-dependent variants in a scene graph.

These methods manage the internal list of scene subgraphs.
Assigns or returns the canvas for a specific child node.
| virtual int VRS::SceneSwitch::childNodes | ( | ) | const [virtual] |
| virtual SceneNode* VRS::SceneSwitch::childNode | ( | int | i | ) | const [virtual] |
Access to all child nodes of the switch node.
| virtual void VRS::SceneSwitch::evaluate | ( | Engine * | engine | ) | [virtual] |
The evaluation request is delegated to all child nodes whose canvas equals the canvas of the current rendering engine.
Reimplemented from VRS::SceneNode.
| virtual SceneNodeVisitor::TraversalFlag VRS::SceneSwitch::traverse | ( | SceneNodeVisitor * | visitor | ) | [virtual] |
The traversal is delegated to all child nodes regardless of the canvas mask.
Reimplemented from VRS::SceneNode.
The bounding box of a canvas switch node is the combined bounding box of the bounding boxes of all children.
Reimplemented from VRS::SceneNode.
| virtual void VRS::SceneSwitch::install | ( | Engine * | engine | ) | [virtual] |
Reimplemented from VRS::SceneNode.
| virtual void VRS::SceneSwitch::deinstall | ( | Engine * | engine | ) | [virtual] |
Installation and deinstallation are not sensitive to the canvas assignments, i.e., all geometry subgraphs are installed resp. deinstalled.
Reimplemented from VRS::SceneNode.

| VRS::SceneSwitch::VRS_SERIALIZABLE | ( | SceneSwitch | ) |
| virtual void VRS::SceneSwitch::acceptChildren | ( | std::vector< Visitable * > & | appendChildrenHere | ) | const [protected, virtual] |
Reimplemented from VRS::Visitable.
