| virtual osg::Vec3 osg::NodeVisitor::getEyePoint | ( | ) | const [inline, virtual] |

| const FrameStamp* osg::NodeVisitor::getFrameStamp | ( | ) | const [inline] |
Get the FrameStamp that this traversal is associated with.
| Node::NodeMask osg::NodeVisitor::getNodeMaskOverride | ( | ) | const [inline] |
Get the NodeMaskOverride mask.
| const NodePath& osg::NodeVisitor::getNodePath | ( | ) | const [inline] |
Get the const NodePath from the top most node applied down to the current Node being visited.
| NodePath& osg::NodeVisitor::getNodePath | ( | ) | [inline] |
Get the non const NodePath from the top most node applied down to the current Node being visited.
| Node::NodeMask osg::NodeVisitor::getTraversalMask | ( | ) | const [inline] |
Get the TraversalMask.
| TraversalMode osg::NodeVisitor::getTraversalMode | ( | ) | const [inline] |
Get the traversal mode.
| int osg::NodeVisitor::getTraversalNumber | ( | ) | const [inline] |
Get the traversal number. Typically used to denote the frame count.
| const Referenced* osg::NodeVisitor::getUserData | ( | ) | const [inline] |
Get const user data.
| Referenced* osg::NodeVisitor::getUserData | ( | ) | [inline] |
Get user data.
| VisitorType osg::NodeVisitor::getVisitorType | ( | ) | const [inline] |
Get the VisitorType.
| void osg::NodeVisitor::popFromNodePath | ( | ) | [inline] |
Method called by osg::Node::accept() method after a call to NodeVisitor::apply(..). Note, the user does not typically call popFromNodePath() as it will be called automatically by the Node::accept() method.
| void osg::NodeVisitor::pushOntoNodePath | ( | Node * | node | ) | [inline] |
Method called by osg::Node::accept() method before a call to the NodeVisitor::apply(..). The back of the list will, therefore, be the current node being visited inside the apply(..), and the rest of the list will be the parental sequence of nodes from the top most node applied down the graph to the current node. Note, the user does not typically call pushNodeOnPath() as it will be called automatically by the Node::accept() method.
| virtual void osg::NodeVisitor::reset | ( | ) | [inline, virtual] |
Method to call to reset visitor. Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.
Reimplemented in osg::CollectOccludersVisitor, osgGA::EventVisitor, osgSim::InsertImpostorsVisitor, osgUtil::CullVisitor, osgUtil::GLObjectsVisitor, osgUtil::IntersectVisitor, osgUtil::Optimizer::StateVisitor, osgUtil::Optimizer::FlattenBillboardVisitor, osgUtil::Optimizer::TextureAtlasVisitor, osgUtil::StatsVisitor, and osgUtil::UpdateVisitor.
| void osg::NodeVisitor::setDatabaseRequestHandler | ( | DatabaseRequestHandler * | handler | ) | [inline] |
Set the handler for database requests.
| void osg::NodeVisitor::setFrameStamp | ( | FrameStamp * | fs | ) | [inline] |
Set the FrameStamp that this traversal is associated with.
| void osg::NodeVisitor::setNodeMaskOverride | ( | Node::NodeMask | mask | ) | [inline] |
Set the NodeMaskOverride mask. Used in validNodeMask() to determine whether to operate on a node or its subgraph, by OR'ing NodeVisitor::_nodeMaskOverride with the Node's own Node::_nodeMask. Typically used to force on nodes which may have been switched off by their own Node::_nodeMask.
| void osg::NodeVisitor::setTraversalMask | ( | Node::NodeMask | mask | ) | [inline] |
Set the TraversalMask of this NodeVisitor. The TraversalMask is used by the NodeVisitor::validNodeMask() method to determine whether to operate on a node and its subgraph. validNodeMask() is called automatically in the Node::accept() method before any call to NodeVisitor::apply(), apply() is only ever called if validNodeMask returns true. Note, if NodeVisitor::_traversalMask is 0 then all operations will be switched off for all nodes. Whereas setting both _traversalMask and _nodeMaskOverride to 0xffffffff will allow a visitor to work on all nodes regardless of their own Node::_nodeMask state.
| void osg::NodeVisitor::setTraversalMode | ( | TraversalMode | mode | ) | [inline] |
Set the traversal mode for Node::traverse() to use when deciding which children of a node to traverse. If a NodeVisitor has been attached via setTraverseVisitor() and the new mode is not TRAVERSE_VISITOR then the attached visitor is detached. Default mode is TRAVERSE_NONE.
| void osg::NodeVisitor::setTraversalNumber | ( | int | fn | ) | [inline] |
Set the traversal number. Typically used to denote the frame count.
| void osg::NodeVisitor::setUserData | ( | Referenced * | obj | ) | [inline] |
Set user data, data must be subclased from Referenced to allow automatic memory handling. If your own data isn't directly subclassed from Referenced then create an adapter object which points to your own objects and handles the memory addressing.
| void osg::NodeVisitor::setVisitorType | ( | VisitorType | type | ) | [inline] |
Set the VisitorType, used to distinguish different visitors during traversal of the scene, typically used in the Node::traverse() method to select which behaviour to use for different types of traversal/visitors.
| void osg::NodeVisitor::traverse | ( | Node & | node | ) | [inline] |
Method for handling traversal of a nodes. If you intend to use the visitor for actively traversing the scene graph then make sure the accept() methods call this method unless they handle traversal directly.
| bool osg::NodeVisitor::validNodeMask | ( | const osg::Node & | node | ) | const [inline] |
Method to called by Node and its subclass' Node::accept() method, if the result is true it is used to cull operations of nodes and their subgraphs. Return true if the result of a bit wise and of the NodeVisitor::_traversalMask with the bit or between NodeVistor::_nodeMaskOverride and the Node::_nodeMask. default values for _traversalMask is 0xffffffff, _nodeMaskOverride is 0x0, and osg::Node::_nodeMask is 0xffffffff.
