Hi Robert,
I see, thanks. However there is some strange behaviour
with the osgText using the State.
If I use the state retrieved from
dynamic_cast<osgViewer::Renderer*>(getCamera()->getRenderer())->getSceneView(0)->getState();
the text drawable is rendered. However If I use the
State given back by the graphic context the text is
sometimes (or most of the time) is not rendered.
I have to investigate why this happens. Maybe you have
some ideas?
Cheers,
Art
