I'm working on a povray render of a model. I've seen the LGEO (not a typo) part library referenced in various places, but I haven't been able to find a working download link.
Is there a current source for an updated version of this part library?
Perhaps this Eurobricks thread is helpful: https://www.eurobricks.com/forum/index.php?/forums/topic/108739-new-parts-for-lgeo-library/
It seems that the lgeo library itself is no longer maintained but this person maintains his own version. The download links are on the first page...
As stated in your "various places" link, the LDraw.org web site maintains an All-In-One-Installer (AIOI) which contains and installs LGEO and is updated in January every year so I assume they use the latest version of LGEO.
BTW, I found an LGEO quirk when launching POV-Ray from within LPub3D which I use for generating building instructions. I kept the screenshot below highlighting how you have to tell LPub3D that LGEO is not available, even though the AIOI installed it:
This is now available on Github.
I was able to find a working download of just the original LGEO library on Eurobricks thanks to some help from the other answerers. I trimmed that down a bit, as that download required integrating some other files in order to work properly. This repo should now work perfectly on its own, but it only includes parts up through 2008 that were created by Lars Uhlmann.
If you are looking for a more complete and cutting edge set of elements, Darats' version (from the accepted answer) seems to be the most current and high quality.
This wiki page describes how to get all the LGEO parts.
