cf - A new script to compare objects

Post #1by cpotting » 26.10.2005, 04:15

A while back I was following this thread http://www.shatters.net/forum/viewtopic.php?t=8072&highlight= where they were discussing an addon for a blue giant. When they mentioned that a single convection cell could be as wide as Jupiter's orbit I was taken aback.

And then I realized something: Celestia lets you zoom around to all these incredible objects, but you never get a sense of how large they are. If you go to Pluto, it appears as a big ball that fills the screen. If you go to Jupiter, it appears as a big ball that fills the screen. If you go to Betelguese, it appears as a big ball that fills the screen.

So I thought I would create a tool that lets you see the comparitive sizes of two objects. It also lets you compare the orientation of two objects (if you're not sure what that means, just try the script - it is much easier seen than explained).

By default it will compare all objects to Earth. I have included a series of activities in the readme file that should familiarize you with how to change the settings and operate the script.

At any rate, I have just uploaded the script to the Motherlode site, so hopefully it will appear there soon.

Let me know what you think, and please pass on any ideas you may have for improvements, additions, etc. that can make it an even better tool.

BTW: I see people include web-style links in their posts (e.g. "I was following this thread where they..." - and you can click on the underlined text to go to the link). Howdyadudat?

Can you copy/paste the script here too, if that's possible?

Oh, to make links you copy the URL, and then type:

[ url = (paste link here)] (insert text for the link, eg "this thread") [/ url ]

(without the spaces)

It's a little large for that. I'm not sure that the moderators would appreciate it. :( Besides, I'm at work... I'd have to wait until tonight.

I've added your script to the CML catalog a few minutes ago:
