changing the sun's size

arlduc · Post #1by **arlduc** » 24.05.2005, 16:32

I needed to enlarge the planets so they could all be seen from outside the entire solar system, so I made a temporary solarsys.ssc in which I multiplied the radius of each planet (and the moon) by 1000. I haven't been able to enlarge the sun though... I tried looking in stars.dat but it's all gibberish. Any suggestions?

thanks
Arlene

Try to define a emissive planetal body with a sun texture around the original sun.

Look in nearstars.stc instead.

You can insert
Radius 6950000
to override the calculated value.

where is that file?... can't find it in the Celestia Resources folder. I'm using the DMG on Mac, maybe it's a little different?

thanks.

I think it was added after v1.3.2 was finalized.
It's available on SourceForge at
http://cvs.sourceforge.net/viewcvs.py/c ... 5&view=log

I fear Radius is new, too.

You may have to consider getting a copy of the Mac version of the v1.4.0 prerelease. It's mentioned in the Prerelease FAQ in the Users Forum.

(But why aren't you using Partiview? Hasn't Brian finished the planet addon yet?

)

yes, I got that version and I'm hoping to slowly work on a QT screencapture function for that... but I'm jumping back and forth right now between that version and 1.3.2, which I was using for a previous production project.

Brian's doing a planet addon? Will have to check on that...

Another thought: I haven't been using Partivew or Celestia that long, but I turned to Celestia for a near-earth asteroid project that I'm doing because I found it easier to pull the Harvard MPC data I needed into an .ssc file than to pull it into Partiview (I couldn't figure out how to pull into Partiview at all). What do you think about it?

thanks.

Making bodies orbit one another in Partiview is one of the things I haven't learned how to do. I agree that it seems to be a lot easier to import orbital definitions into Celestia.
