• osg::Group - example of the Composite Design Pattern


• osg::Transform - base for class nodes which transform their subgraph
• osg::MatrixTransform - uses a 4x4 matrix for the transform
• osg::PositionAttitudeTransform - uses a Vec3 position, Quat rotation for the attitude, and Vec3 for a pivot point.
• osg::DOFTransform - OpenFlight style Degree of Freedom node


• osg::Geode - leaf node from which drawable leaves are hung
• osg::Billboard - orientates associated drawables to face the viewer


• osg::LOD - level of detail node
• osg::Impostor - adds support for hierarchical image chaching


• osg::Switch - controls which of the children are on or off


• osg::Sequence - automatically steps through children


• osg::LightSource - positions an osg::Light in the scene


• osg::ClipNode - positions osg::ClipPlane planes in the scene


• osg::Projection - overrides the projection matrix (useful for HUD's)


• osg::OccluderNode - positions convex planer occluders and convex planer portals in the scene
