Ok, but I need the exact vector. For example:
x: 0,5 y: -0,3 z: 0,1
A negative rotation is needed to know if the object is turning the other way.

"tilt" is a bit weird, it goes:
0 up to 179.999 and then it switchs to -179.999 and then up to 0 again. So the difference is wrong when one variable is in the positive area and one in the negative. For example:
copy = 179
my.pan = -160
speedX = abs(my.pan - copy);
SpeedX is 339 then.

It's all a bit more complex as it seems
