I am please to announce (finally) a release of OOliteInfo3D

http://www.theramist.co.uk/blog/?p=128

I've been struggling for some time to create an installer package for this as most of the windows exe creators for Python only seem to like 32bit and the mac version of VPython has trouble with 64bit.
The intrepid amongst you can simply download the source file from the link above, install Python and vPython http://www.vpython.org/
There should be no other dependencies as all data is generated procedurally.

Running on a mac can be tricky. Depending on which version of Python you are using, and the version of VPython you might need to run as follows:
arch -i386 python ooliteinfo3d.py

There is a new release of VPython which in theory should address these issues but I have been unable to test it as yet.

Also this prog is a bit slow to run. It seems okay on my MacBook Pro with Intel graphics 4GB and my Core2 Duo work PC with an Nvidia. Your millage may vary which is why I've added the option to turn off the grid and the jump routes.

Rotate by holding down the right mouse button, zoom by holding down the middle.
Click on planets to show their info. Click again to hide it.
Pressing <C> will recenter the display but not the zoom (vPython quirks).

When you click on a planet it will show an opaque sphere to indicate the 7LY jump area from that planet.

Lastly I have created a Z coordinate that basically just uses the government number and seems to give a good spread on the planets that overlap.

It's not perfect but give it a go.

Thanks to PhantorGorth for our many conversations on the procedurally generated data and a nice bit of healthy competition.
Also thanks to whoever created TextElite as this helped me work out some of the more odd bits of data.

Intersting....

Is your OS 32 or 64 bit?

I've just read on the vpython website that this is a known issue with Ubuntu.

Apparently an issue concerning the NVidia drivers.
Have a look at the bottom on this page unt her older versions heading:
http://www.vpython.org/contents/download_linux.html

I'm currently trying to get it running on my Linux virtual. I honestly thought that Linux would run this the easiest.

Just for the record:
Debian GNU/Linux 7.0 - amd64
python 2.7.3 + python-visual

seems kind to work. Able to resize and spin the grid, but having the star name labels permanantly displayed.

That shouldn't happen.
It initially displays all the star labels in order to get round an issue where the labels never displayed.
I'll have another look at the code and try to sort it out.

So, if you try turning the labels on and off do they dissapear?

Partial success here:

clearly a dependency/import issue, but I'm not sure where "text" is supposed to come from . . . any ideas?

Hmmmm...

Text should be a standard function of vPython. Which version have you got installed?

Debian wheezy package
ii python-visual 1:5.12-1.5 i386 VPython 3D scientific visualization library
looks like the packagers might have gone mad & split it up or something, I'll see if I can find out, thanks.

I've got an odd feeling that the text module was only available in later releases.
I'll have a check of the release notes.
