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. Roberto ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
