Hmm...... _definately_ is a strong concept ..... FWIW I doubt if the DIS protocol is much if any better then a clientside Kalman Filter except for reducing 'net traffic'. So the tradeoff is where do you want to expend the computing time. It does take a 'leap of faith' though :-) Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
