Nasa ISS model hightly detailled

[bh]

Amazing pictures linuxman... this is going to be the definitive model of the ISS for sure. Can't wait to try.

[Hungry4info]

Absolutely stunning!

Though if I may (again), Node 3 will be on Node 1 port, with Cupola on Node 3 nadir.

While the pictures are looking very nice, one question is hard to deny:

What's the typical framerate for these super-detailed monsters??

I fear it will be too much for my meagre setup...

For the moment under windows vista 64 its seems to be between 12 to 15 IPS (with an old nvidia driver ), the station appears after 25 second .

25 to 30 IPS now (11 feb)

I will wait iss pictures in a few days to see exactly there is the right emplacement

here is the node 3 with cupola close and open




It is good?

I don't know at what time is the cupola moved and his windows are opened

[Hungry4info]

Yeah, that looks almost accurate.

Cupula has already been moved, but the windows aren't yet open. They mentioned in a briefing yesterday that we'll have our first images from Cupola wither Wednesday or Thursday. I don't know if that's when the windows open or not though =s.

Edit: Just noticed Cupola is turned at an odd angle. It is angled such that two vertices of the hexagon are aligned Forward-Aft, as opposed to Port-Starboard as it seems yours is.

(it's currently covered in thermal blankets that will be removed later).

Is there a way to sync up to the real-time orbit position? I can manage it with the old ISS.ssc file by editing the relevant parameters (epoch, eccentricity, etc) however when I try this with this new ISS.ssc file I lose the ISS altogether and have to put the original .ssc file back.

Excellent model. Thank you very much.

Can I request a 'static' model of the ISS as it is now with and without shuttle?

If you read the Help -> Controls menu item you'll see that the "Y" key is used to SYNC to an object:

Y : Orbit the selected object at a rate synced to its rotation

(no need to edit the SSC file)

Not sure I'm following you. This will cause the ISS model in Celestia to orbit the Earth pretty much exactly as the real ISS is orbiting the Earth?

You said:

which in Celestia is done by going to the object and pressing the Y key.
Please describe exactly what it is you want to do.
To "sync up to the real-time orbit position" has a specific meaning in Celestia related to the behaviour of the observer relative to the observed object.

I'm confused about what exactly it is that you want to do. You need to describe exactly what you want to achieve.

Sorry, I didn't explain it properly. I would like to take this model by Linuxman and put it in an obrit in the Celestia program that matches the orbit of the real non-Celestia NASA-built ISS. When I apply the process that I use to change the orbit of Celestia's default ISS spacecraft – which works well (viewtopic.php?f=2&t=12582&hilit=iss+position#p105241) - to Linuxman's model it does not seem to work. In fact after modifying Linuxman's ISS.ssc file his ISS disappears altogether.

Apologies for the confusion once again.

[Chuft-Captain]

Please post your modified SSC file (enclosed in code tags) so that we can see what you're doing wrong. It's a bit hard for anyone to help if we cannot see exactly what you've done.

Below is the portion of Linuxman's ISS.ssc file that is the focus of the modification process (to create the orbit held by the real ISS) advised here viewtopic.php?f=2&t=12582&hilit=iss+position#p105241. This process works fine for the ISS.ssc file that comes with Celestia 1.6.0. The search tag for Linuxman's model is Zarya and pre-modification it shows and looks great, but I can't get it to the correct orbit when I modify it's ssc file. It doesn't even find Zarya. I even removed the ISS folder from Celestia's "extras-standard" folder thinking there might be a clash but this made no difference. Sorry, I don't know what "enclosed in code tags" means.

This is from the ssc file obtained from the Linuxman download, I have not changed the values here but per the process it is a simple matter of going to Heavens Above and switching to the latest values of the parameters under EllipticalOrbit. There is much more information after this intial portion of the file that does not occur in the ssc file that comes with Celestia 1.6.0. However, per the process there is no indication of it being relevant.

You may have made a typo. When you make a syntax error in a Celestia SSC file, everything following the error will fail.
It's also possible that your editor has saved the file with an additional .txt file extension. What OS are you using, and which editor?

If you are using Windows XP:

go to an explorer window, and select Tools -> Folder Options
Select the View Tab
Make sure that "Hide extensions for known file types" is un-ticked.
Now view your new SSC file in explorer and make sure that it doesn't have an additional .txt extension.

To insert code in a code block, click on the CODE button above the edit window when posting your message. This will insert beginning and ending code tags into the edit window. The cursor will be positioned in between the 2 tags.
Paste your code at the cursor.

Thanks, I'll look into that and get back. I'm using Windows 7 and MS Word which does give me a formatting pop-up choice when I save following the edit. Not sure what it's doing, I just click "Yes" so that is saves. So it looks like something is going on there.

[Chuft-Captain]

That's the problem --- You're using WORD, which embeds a whole lot of formatting characters in the file, effectively corrupting it for Celestia use.

You MUST use a plain text editor to edit SSC files.
Wordpad is fine, Notepad will also work.
If you're planning on doing a lot of this, then I would recommend that you download and use something like Notepad++, though you'll be fine with Wordpad in the meantime.

Hi scroll,

if that is the whole definition that you posted, then there is definitely a "}" missing at the end of the definition.

"{" indicate for Celestia the beginning of a defintion of parameters and "}" signals the end of that. You have 2 "{" but only 1 "}", so you definition of Zarya is not finished for Celestia and it stops to interpret it.

You can also always call up the console on Celestia startup by typing a "~" in the Celestia window. Then you will normally find an error message, where Celestia has encountered an error in a file and know where you have to look.

Regards,

Guckytos
