should be applied to a node or its child with the new osg::Node::setCullingActive() flag. A mechanism has been implemented so that if child has its culling disabled then their parents, all the way up to the root are also have their culling implicitly disabled. The osg::CullVisitor has updated to take account of both the explicit control via setCullingActive and the implicit culling disabling through children being disabled. This feature is useful for nodes which don't have a bounding volume to cull against, earth sky implementations and light sources. The default osg::Node::_cullingActive is true, i.e. culling is enabled by default.
Welcome to the Open Scene Graph (OSG). For compiling the OSG under all platforms (Linux, FreeBSD, IRIX, Windows and Mac) please read INSTALL. For general documentation, distribution contents, and plugin dependancies please read index.html in your prefered browser. index.html also has links to INSTALL, making it easier for Windows users which might find the lack of file extensions on text files awkward.
