Hi,
I fully agree with the MRP idea. It is just an arbitrary point in the model.
Alan,
I don't see a real argument in this translation you talk about. The computonal
cost of this single translation is peanuts compared to the computations done
elsewhere in flightgear.
Also If you prefer to
I've been watching this thread with some interest. May I say how impressed I
am with all that has been achieved so far.
FWIW I thought I describe my experience of modelling a 3d aircraft. At the
outset I used the nose as the origin of both the model and the FDM (YASIM in
this case). The 3d

If there was a RESET capability for the filters, it would be driven by
