I am currently trying to use/extend resonances to make plots for Wikipedia of resonant Solar System bodies in the Sun-planet orbit rotating frame, like so:
resin_animation_test.mp4
Right now I'm doing that from Solex output, which can provide Cartesian coordinates for the small body in resonance and the larger body it is librating around. Those coordinates can then be rotated into the orbit frame and the positions of both bodies plotted.
Having the bodies object provide Cartesian positions (ideally in ICRS coordinates, but I'll take any other consistent system) would make this more convenient. While positions can be calculated from the osculating orbital elements, it does add an extra step which seems redundant considering the positions are available from the underlying REBOUND integrator.
