Is there a way to add a model so that it can be seen when looking at the galaxy from outside?

I want to add a map for a game that will show up as borders floating in the galaxy.

Is this possible?

Yes.

A model that holds a flat picture is available on the MotherLode, about halfway down the OA page at
http://www.celestiamotherlode.net/catal ... onsarm.php

So long as this is for a non-commercial purpose, and 2D outlines are OK, you could draw on Steve's picture.
(see http://www.celestiamotherlode.net/catal ... don_id=823 )
Otherwise, you'll have to come up with your own image.

Adding 3D borders would be somewhat more work, since you'd have to create models for them. Simple spherical models are easy, but complex shapes might not be.

Here's an example that was quickly thrown together to give some idea of the distribution of OA polities

Selden,

those balls are looking interesting, as markers. What are they ? Textures on spheres, or meshes ? Where can I find this addon ?

They're cmod models drawn using lines between vertices instead of triangular patches (linelist instead of trilist). I just changed the colors in the ASCII CMOD sphere models that I used for my coordinate sphere graticule addon.

The coordinate sphere addon is on my graticules page at http://www.lepp.cornell.edu/~seb/celest ... les.html#4

The OA map was just a quick hack that was only mentioned on the OA mailing list. It's available at http://www.lepp.cornell.edu/~seb/celest ... inions.zip

well it is for a RPG game I am creating with a few friends. I had an idea for a cool webpage art and wanted to use celestia to show the galaxy and use a image to show the borders of the empires etc.

Maybe for a later time, when i know celestia a little better, I will add transparent shapes that show the boundries of the setting.

I'll look at his model and see if I can figure out how to work from there.
