Orientation has no meaning in space.  How is it going to handle that?  Really all you can take into account is velocity and acceleration.  Acceleration being the important one.

Ya whatever..

Relative orientation then it is, i can map anything that comes along as long as i can compute something that results in a relative positional change.

I think we all still believe that a space fighter pilot still has a somewhat wired feeling of "selvelocation" inside the weightless vast of space.

As well as there is some kind of vodo mechanism that saves him from being crushed by acceleration. ( our silly little world will give us a sensation that down is where our butt is so we need to simulate the fighters relocation to this because otherwise or mind will not make believe ) since i cannot turn, bank, yaw, roll whatever indefinably with the mechanism  i need to trick the mind into believing this happens.

Basically what i can do is simulate changes in relative velocity so any vectorial change will result in a swipe to this direction followed by a (as slow as possible ) return to zero.

However, all this can be changed by setup ( and software change since all electronic units can be updated on the fly ).

So don´t worry once the machanical forces of that mechanism work out, the rest is code...

Relative to what?  I mean in a flight sim, if you have a 30 degree bank but constant velocity, that affects things.  The chair likely leans or something.  But in FSO, there's no need to because there's no gravity.  If the chair was suddenly arbitrarily tilted to one side, I'd wonder what the heck it was doing.  The only time the chair should react is when there's an acceleration, to simulate the G forces.

i think he means monitoring the delta in the velocity vector. if there is a lot of change in the vector between one timeframe and another, (not really frame by frame because i doubt the mechanics could actuate fast enough), probably about every 250-500ms. the amount of change signifies how fast of an axis of the simulator shall actuate. now if theres not very much change in velocity then the platform very slowly tries to recenter itself for the next big manuver. for changes in magnitude you can simulate g forces by playing with the pitch axis of the simulator. for the purpose of a space sim i think orientation of the spacecraft is less important, unless you need the vector in a different frame of reference (such as relative to the ship). you cant simulate zero g, that is unless you dont want to drop the simulator out of the back of a c130 and fly while in freefall . for simulators its less about directly converting virtual movement to mechanical movement, but rather convert virtual movement to perceived movement. simply looking at a screen with a simulated world on it is enough to trick the mind into thinking that what they see is whats going on. the simulator plays on that by providing inertial stimuli.

If so, then we're saying the same things, but there's no need to say things like 'delta in velocity vector' or 'change in position' when there's already words for those things

Nuke, your right there needs to be quit some soothing inbetween ( the mecanics will be reasonably fast, it can move approx 8 cm in only 1 second. The trick will be to make it feel right all the time and i think you really need to do some trial & error to get it right.

Not a big deal however since i would like to have my code arranged in a way that everyone can setup his personal and preferred response.. ( and although movements )

reducing the seat to 2DOF would however reduce cost and afford a lot. What do you think? Does the seat need to move up and down ( this motion is technically demanding, force wise )

in 2DOF it would only tilt and pitch. ( or should it have yaw as 3rd dimension this would be a lot easier )
