For the default the look-at point should be a fixed point within the aircraft reference frame or the Aircraft Center of Gravity. this can and probably should be an option The ability to have an arbritrary camera orientation is 'sugar' < read 'eye candy' > that can be added later BTW - Good to see you made it through to today even after having used a computer yesterday :-) Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
