Red Orbit lines

I suspect this is probably a well known bug...

If you go to a moon or planet with orbits selected, you end up seeing that body's orbit as a red line crossing the screen. Is there a way to remove the target body's orbit from the field of view around its primary when you're really close to it (say, when its angular diameter onscreen is more than 1 degree?)

This is the sort of thing I mean:

The red lines there are Sinope's orbit (ignore the apparently blue bits in the red line, that's just the JPEG image compression) - it'd be nice if at this range those were invisible but the other orbits could still be seen...

Don't know that I would call this a "bug", since you are more than likely seeing two different sides of the elipse that is in fact it's orbital path. If you zoom out and rotate the view, you would see this.

Eliminating a single objects orbit from being rendered is not currently possible in Celestia, as you may know. Thus, this would be a feature request -- either as user-specified selections, or as you suggest, automatically using the objects angular diameter on-screen.

Well, it's a bug from the perspective that the red orbit line should be going right through the body being targeted, not hanging out below it as they are in that picture :).

So would a feature request go in the Users forum then?

Sorry, yes, I agree. But the topic was about red lines :wink: .

I'm not sure why the orbit paths don't go through an object, instead of being displayed as they are.

Chris? Is this a graphics hardware / software limitation, or something that is on your to-fix list? Or should it be added to the SF Bug Tracker?

Yes, the User's forum is the best place to post a feature request.

Please read the Preliminary User's FAQ. Q/A #14

(althrough it's expected to be fixed soon.)

Thanks. Although this problem crops up more for small objects than large ones.

BTW, the links in the FAQ don't seem to work - are they're pointing to the right IP address? It only worked when I replaced the IP address there with http://www.shatters.net

Oh Evil One,

Thanks for pointing out the URL problems.
I've fixed them.
