Thanks Fred, I already know all that stuff about facets, normal 
smoothing and so on :-)
The question regards the possibility (or impossibility) of FlightGear 
(or the OpenGL interface) to proper render smoothed shadows. Those faces 
in the image are already normal-smoothed, hence pixel colors are 
interpolated between contiguous edges; you can clearly see how the grey 
color of the rounded surfaces is smooth shaded. But the shadows are not. 
Is this a FlightGear related issue or other graphic cards do smooth 
those shadows too?

Image http://www.laubfrosch.it/public/tmp/tie-005.jpg shows a rounded 
surface which is not normal-smoothed either. Look at the difference. 
That does pertain to surface colour interpolation only. My question 
instead is about the shadows.
