HI Art,
As osg::GraphicsContext "has a" osg::State object, while the
Viewer/Composite class "has a" collections one or more
GraphicsContexts virtue of the Cameras that they maintain. The viewer
classes have a convenience method getContexts(ViewerBase:Contexts&)
which you can use to get the contexts. i.e.
Viewer::Contexts contexts;
viewer.getContexts(contexts);
for(Viewer::Contexts::iterator itr = contexts.begin();
itr != contexts.end();
++itr)
{
osg::GraphicsContext* context = *itr;
osg::State* state = context->getState();
// do with me what you will
}
