Hi Katja, osgText uses a texture atlas to store it's glyphs and separate quads to pull out the correct part of the texture atlas to get individual text characters, this makes it impossible to just pull the text texture directly and apply it to an ordinary geometry as the texture coordinates would be all over the place.
All is not lost though, the OSG supports render to texture, so it would be possible for you to render a text subgraph and any other geometry you want to a texture and then apply this texture to your geometry. The OSG provides an osgSim::OverlayNode to help make this task even more straight forward as it will manage the render to texture setup for you. See osgsimulation exampe for an example of it in action. Robert.
