If you're only doing one frame, then odds are you aren't looking to do graphics. So investigate some of the offscreen rendering possibilities. GLUT is not well-suited for this; two options are OSMesa, or writing your own Win32/WGL wrappers.

Generally the approach is to create an invisible window in order to get a context, and then do all rendering to FBOs.
