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.

Hi,
I want to map a osgText to a geometry, for example a sphere. My idea was to
get a texture out of osgText and map the texture to a geometry. Is there a
better way to do this? And how do I get a texture out of osgText?
thanks in advance
Katja
