This isn't entirely a showstopper. Polygon offset works for lines, but you have to enable it explicitly and there are some confusing rules regarding wide lines. > The second is that OpenGC use changing of projection in each Gauge > component to clip out the stuff which doesn't belong to gauge. Hrm. That's nastier. David is right, that clip planes can be very slow on some hardware, and cause interactions on others. NVidia cards actually use one of the texture units to do user clip planes (which is awfully elegant, but really weird). If it's entirely 2D rendering, though, and all that it's drawing is lines, then doing the clipping yourself is really easy and probably not too slow. But maybe you're right, that a custom-built FlightGear EFIS would be simpler. Andy -- Andrew J.
