Celestia Forums

Vincent, I tried changing celestia.cfg to "allow" and 1.5 still crashes immediately when reading the large file. Your recommendation is to go to the SVN version? This is a program I've been working on for several years that I want to distribute to the community in the near future. Thanks for your he...

I downloaded 1.5 for the Mac OS and discovered that now none of my large programs written over the past couple years work at all. They either immediately crash Celestia or simply exit after a brief pause The versions range in size to 150K to 180K. They all worked perfectly on the previous version. I...

Uh-oh. This version crashes almost immediately without doing anything except using the arrow keys.

Well, I can appreciate this is probably not a burning issue with most users, but I believe this version may help me complete a large project I've been working on for several years .

Henry

Great! Can you tell me where that's available for Mac OX? I couldn't find it with an Internet search.

I'd be grateful if someone could explain the Celestia "obs:getlocationflags()". I can't get it to work, probably because I don't understand it. I would think locations would attached to an object, and not an observer. But when I make the call on the observer object as documented, I don't seem to get...

The "surface" is a reference spheroid I assume?

I hope I didn't sound ungrateful. I realize that many, many hours must have gone into the compilation of this data and I'm very thankful to be able to take advantage of it. Of course my script will point this out with credit given. BTW, in writing the parser for the locs.ssc files I noticed somethin...

I'm currently in the final stages in completed a ~190K script for Celestia I call "Celestia Explorer" which I plan to make freely available. I'm writing to make sure there are no copyright or other infringements. Unfortunately, why that might even be possible will take some explanation. One of the t...

Selden, Remember that most of this is invisible and covers hundreds of light years. I'm mostly modeling changes in the ISM. For example the "Local Fluff" is .1 atoms per cubic cm and the "local bubble" is .001 atoms per cubic cm. However your comment directly addresses my original question above and...

Selden, You're pretty close. I model a gas cloud by a table of spheres, which can be overlapping. Each sphere has a "priority" which means I can model a gas shell with a density inside and another for the shell. For example the "local bubble" only takes about 15 spheres, even though it has a very co...

In searching the forum for discussions about nebulas, I've see the various comments on creating volumetric constructs. In my program I started out modeling invisible things externally to Celestia, for example the the "Local Fluff." The models are held internally in my celx program. This works fine b...

Thanks Frank! I had talked to someone else who told me it was impossible, so I didn't bother to do the obvious. Wow, I'd be happy with a beep, but you're right. Very sophisticated. There goes the last of my free time.

I'm putting the finishing touches on a new version of the Celestia Explorer script that contains bug fixes and some major new features. I thought I'd mention some of what I'm finalizing to see if anyone had a comment. My objective in writing this script is to enhance the sense of being in the actual...

If this is a postfix for a generic rotation file then .rot seems best to me. The reason is that "rotation" is currently being used in the documentation as an alias for a quaternion, so this would be a generalization of the term rotation in that quaternion becomes only one instance of the type Celest...

Well, of course, what the Celestia documentation refers to as "rotations" are in fact quaternions. But as far as I know, all the operations that are defined for quaternions are about setting the orientation of the observer, not the orientation of a model. I have no problem with using quaternions. Th...

Selden, I've reread the "pointing hubble" thread you recommended and found I'd missed the salient point. To point hubble you have to exit Celestia, go to the ssc text file, edit its parameters, and then reload Celestia. Here's my real question (although I think I already know the answer): Are the da...

As far as I know, the IO capability of Lua does not include a sound interface. It's not possible to even get a peep out my Mac in Celestia which, like most modern computers, has a very sophisticated voice synthesizer. Celestia has beautiful graphics, but it's a shame that Lua programmers can't acces...

CelestiaExplorer does that, except to move out of the ship (which you can't do now) you would see the vehicle you have been traveling in. That and simulating lander physics might be an interesting addition, but it sounds like this might be more a project for the next version of Celestia.

Henry

I read the "pointing hubble" thread but now I'm really confused. Is there any documentation for version 1.5.0 available yet?
