Namespaces

namespace  osgTerrain
 The osgTerrain library is a NodeKit that provides geospecifc terrain rendering support.
namespace  osg
 The core osg library provides the basic scene graph classes such as Nodes, State and Drawables, and maths and general helper classes.

Macros

#define OSG_NODE   1
#define META_Node(library, name)
 META_Node macro define the standard clone, isSameKindAs, className and accept methods.

Typedefs

typedef std::vector< Node * > osg::NodePath
 A vector of Nodes pointers which is used to describe the path from a root node to a descendant.
typedef std::vector< NodePathosg::NodePathList
 A vector of NodePath, typically used to describe all the paths from a node to the potential root nodes it has.
typedef std::vector< Matrixosg::MatrixList
 A vector of NodePath, typically used to describe all the paths from a node to the potential root nodes it has.

META_Node macro define the standard clone, isSameKindAs, className and accept methods.

Use when subclassing from Node to make it more convenient to define the required pure virtual methods.
