Does anyone know of where in the FG code base I can find a function that takes a position in 3-space and gives the resulting position after a pitch/roll/yaw set of rotations?
In case you're wondering, this is needed by the new submodel system. A submodel is an object that has a position (x,y,z) defined relative to the center of the user aircraft (say a left-wing drop tank, which is attached to the airplane at 1,-8,-3, where x is forward, y is right, and z is up). If the airplane rotates to a certain pitch/roll/yaw, what is the new location of the drop tank? I need to know this so the drop tank can be released from the correct world coordinates (lat,lon,alt) no matter the aircraft's orientation. I assume this function already exists somewhere, either in SimGear or in an FDM. From what I've managed to learn about the matrices involved, I see that there are many more ways of getting this wrong than there are of getting it right :) Especially for me. I'm flexible on the coordinate system. I know axis conventions might be different.
