That's exactly right. Furthermore, if the VRP is set to the empty weight CG for an aircraft flight model, and the 3D modeler talks with the flight modeler to communicate where exactly the empty weight CG is (since it is the flight modeler that will be setting this location based on physical parameters), then everyone is happy, as well. The VRP code now in JSBSim simply allows an agreed upon point to be reported to FlightGear - whether it's the empty weight CG, or the nose tip, or the left wingtip, as long as it is agreed upon between the 3D modeler and the flight modeler, the rendition will come out looking right. There's nothing nefarious about the new code in JSBSim. Nothing that leads to a dead end. The big question seems to be about where the common reference point should be. Think about that one. Think about what each modeler will know. Think about what both will know. Think about whether the common visual reference should be the same (a convention) across all models so it doesn't lead to confusion.
