IMHO, that is about as clear an explanation as you are going to get;
Jon has all but written the code for you.

I would suggest that you just forget about extrapolation for now and
get a fixed timestep loop working. That looks something like this:

  ode_time = gettime()
  while (true) {
    render_the_scene();
    curr_time = gettime();
    while (ode_time < curr_time) {
      dWorldQuickStep(ode_timestep)
      ode_time += ode_timestep;
    }
  }

Get that working first and see how it looks; depending on your needs
it might be perfectly acceptable. If you start noticing temporal
aliasing or lag, then you can start looking for alternatives. Have you
done this already?
