Hi Frank,
Take a look at the demos in OpenGL, particularly:
OpenGL-ctypes/OpenGL/Demo/GLUT/tom/conesave.py
which is a little GLUT application that renders into a GLUT windows and
then allows you to save it. That's raster operation though (i.e.
produces a PNG or JPG). Raster operations can only save a portion of
the screen as rendered, so if you want a higher resolution image you
need to make a larger window. If you want to get more advanced you can
try using an off-screen buffer (pbuffer or MESA) for the rendering,
which may (depending on implementation) allow for higher resolutions.
If you want a true vector graphic (PS, EPS) you'll need to use something
like GL2PS.
