Detailed Description

Base class for all internal nodes in the scene graph.

Provides interface for most common node operations (Composite Pattern).

Member Typedef Documentation

typedef std::vector<std::string> osg::Node::DescriptionList

A vector of std::string's which are used to describe the object.

typedef unsigned int osg::Node::NodeMask

This is a set of bits (flags) that represent the Node.

The default value is 0xffffffff (all bits set).

The most common use of these is during traversal of the scene graph. For instance, when traversing the scene graph the osg::NodeVisitor does a bitwise AND of its TraversalMask with the Node::s NodeMask to determine if the Node should be processed/traversed.

For example, if a Node has a NodeMask value of 0x02 (only 2nd bit set) and the osg::Camera has a CullMask of 0x4 (2nd bit not set) then during cull traversal, which takes it's TraversalMask from the Camera's CullMask, the node and any children would be ignored and thereby treated as "culled" and thus not rendered. Conversely, if the osg::Camera CullMask were 0x3 (2nd bit set) then the node would be processed and child Nodes would be examined.

typedef std::vector<Group*> osg::Node::ParentList

A vector of osg::Group pointers which is used to store the parent(s) of node.

Constructor & Destructor Documentation

osg::Node::Node ( )

Construct a node.

Initialize the parent list to empty, node name to "" and bounding sphere dirty flag to true.

osg::Node::Node ( const Node ,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::Node::~Node ( )
protectedvirtual

Node destructor.

Note, is protected so that Nodes cannot be deleted other than by being dereferenced and the reference count being zero (see osg::Referenced), preventing the deletion of nodes which are still in use. This also means that Nodes cannot be created on stack i.e Node node will not compile, forcing all nodes to be created on the heap i.e Node* node = new Node().
