Although it might be easy to understand, this definitely misses the idea of a reference point. When you're modelling an aircraft, nothing it that much likely to vary than the nose and the tail because the manufacturer probably has modified the plane and there exist different versions with different noses (this is quite likely to occur), there may be inaccurate data on the nose geometry, when modelling a plane in low resolution for FlightGear you have to take some restrictions into account that affect the geometry of the nose, it depends on the taste of the person modelling the plane, .... The nose simply is a point of less relevance to the aircraft compared to things like wing root for example. After modifications to the wing root of a (real) airplane you are still able to extrapolate the 'original' reference point. This is impossible with the nose in most cases, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
