Just having a bit of fun with my new atmosphere code . . .

to much work on Celestia....
He has finally flipped

I'm happy another bug is removed.

I think it's time for a new prerelease.

but what does it do when you wrap it around the Borg Cube???

It only works for ellipsoids . . . I could probably come up with something that works for any mesh over a limited range of distances. However, I'm not going to bother . . . There are other improvements that I'm making to atmospheres that require a more regular geometry. Also, the laws of physics have obliged my laziness by only permitting atmospheres around objects with enough gravity to be compressed into spheroids.

I understand. I forgot to include a winking smiley. I was just remembering how the atmosphere looked when I was trying to apply the various planet rendering options (like nightlights) to the Cube. If it weren't for the sunrise/sunset effect it would have looked like a reasonable forcefield.

I'll omit the details of my usual plea for more generic surface texture handling for 3D meshes...

speaking of atmospheres, how is the hole in the sky problem coming?

[the guardian]

Very nice work. Will there be an update to the current solarsystem.ssc file? With all Jovians included with atmospheres?

[chris]

Updating the Jovian planets with atmospheres:
Yes, I will do this . . . However, I need to check out some Voyager and Galileo images of the planets to get a feel for what looks the most realistic. I seem to recall all the pictures showing a well defined edge to the planets, which indicates to me that the 'height' of the atmosphere in Celestia should be small.

Hole in the sky:
Yes, I'm in the process of fixing it now.

keep in mind the majority of those nasa pics are with the sun behind the probe, so there's little to no highlight of the outer edge of their atmospheres. i suggest looking for backlit images where you hardly see any of the planet to get a good guess on the thickness.

and here's an amazing animation of IO in jupiter's shadow.

Someone mentioned the Borg?

It's nice to have that atmosphere bug fixed, finally it'll look good for objects placed directly on the surface!!

Completely off topic, but- Anyone see the eclipse last night/this morning?

Perfect texture for Anti-De Sitter space;-)

No, I am definitely NOT telling what this is...

This subject seems to be overreacting;-)

Yes, I saw that topic just after I posted my first reply!
