That's the trick... Making the screen rotate at a specific rate and having the trail positions draw relative to this rotation.
Open up the Shoemaker-Levy 9 simulation. These trails are drawn relative to the 'absolute world' (which is almost the same as relative to the sun, since its moving the least).
Right click on Jupiter and select "Set to Center"
Now all the trails are drawn relative to Jupiter.
To make the rotating frame work I need to do this, but with rotation instead of just position.
(And the "Set to Center" mode has a few bugs that are unresolved. For example: The comet impact marks don't always show up in this mode)
