I'm not sure exactly what this is for. I can (and probably should) export the C.G. position for the view code to use appropriately. But the VRP stuff seems like a double-correction. It's basically identical to the view center offset stuff, isn't it?
It's the location on the plane where the FDM reports the lon/lat/alt. It's kind-of a nifty idea, actually.
True, but... This is a chunk of calculations running every frame. In the olden days, the cost would be
too high. Our Aerodynamic modelers always seemed to know where the empty weight CG was every
frame without additional calculations. That said, we made the graphic artists translate the visual model
such that the 0,0,0 point for the model was the empty weight CG. This operation was done once. We
were always able to put those spare calculations to good use adding fidelity elsewhere.
Realize that I don't have a dog in this fight. I'm just conveying a bit of simulation history. It's up to
you folks to decide what to do with the blessings of Moore's law... :-)
