they treat the head only as a mass on a spring,
and completely disregard the physiology of the
eye/equilibrium organ/brain system.
Maybe I should clarify: My idea was not that view changes
based on acceleration/inertia should be even more

Umm, but the videos taken by them don't show what their
brain sees. Our brain is a *lot* better at stabilizing the
image than most of the camera stabilizers. Simulating

As Melchior said, the head-shake mechanism does indeed regard the head as a
mass and a (damped) spring, but it's a bit more sophisticated than that -
the resistance of the neck muscles are modelled as well.

it might be worth reconsidering the up/down movement. While
pulling back on the yoke/stick may make a jet fighter shoot upwards,
with a regular plane it's just as likely intended to slow the plane down.
Yes, this was targeted at fighter jets. In

Hi Everybody,
One thing that probably stands out at this year's FlightGear booth is that we
had 6 more monitors than presenters, and that the monitor to presenter ratio
at the booth is 3:1. This leaves the question as to how many presenters were
at the booth, given that this number is a prime.
Torsten, Durk, and one developer who again wishes to remain anonymous,
had a
pretty good show today, with a bit of a slow start. Initially, we had
some
performance issues on the windows machine, and some minor bugs to
solve, but
these problems were gradually resolved during the day.
Many

Hi Syd and all,
I could not go to bed when I saw that you uploaded the first files of
this helo to CVS, waited some time, downloaded and tested it.
Thank you very much. I enjoyed my test-flights (used some different
airports on the world with different winds) very much.

To have a R22 in the sim is especially nice as you can find so much
