LDraw and LGEO licences


LDraw and LGEO licences
#1
I'm interested to understand the licensing arrangement for the LGEO library, especially as this is different to the LDraw library

The statement at the top of each of the LGEO inc files says:
"It is provided for private non-commercial use only."

I'm curious to understand this limitation, as the majority of the LDraw parts are released under the Creative Commons Attribution Licence 2.0 which allows commercial use.

Is Lutz Uhlmann still the primary maintainer of this library? What are the options for requesting a less restrictive license?

BTW: I noticed that the main reference on the LDraw website to the LGEO library is currently a dead link:
http://www.digitalbricks.org/lgeo.html

How do the parts created by Darats relate to the original LGEO library? Could these potentially be re-released under a different license?

I'm also curious to know why I keep spelling licence differently every other sentence Smile

Hi,

My parts belongs to the LGEO library because they have been made to be used the exact same way. I have only copy/paste original headers.
I actually don't care about licensing because as soon as it is made available for free, people will use it for any purpose whaterver the licensing...

I am open to change the headers to fit ldraw license, that sound more logical to me.

My ultimate goal, would be to replace 100% of original LGEO parts, to get rid of this multi boolean operation levels (which should speed up rendering times) and to be able to have round edges anywhere on the parts.

But, I want to insist that my LGEO parts are still WIP and because of lack of time due to paternity, I don't know when I will be able to make it fully compatible with Owen's ones and integrable in the AIOI.

I'm looking for a link where I can download the original LGEO parts without all the other additions by different people, too.

Hi Michael,

here is a link to an archived version of it: https://web.archive.org/web/201203201730...a/lgeo.zip

I think it's the last official, original version of this library.

Thank you! I did not know that archive.org saves ZIP files too.

There is a newer snapshot by archive.org for lgeo.html from 2014-10-20
https://web.archive.org/web/201410202337.../lgeo.html
, but it points to a dead download link.

So indeed the link you provided above of 2012-03-20 is the chronologically last working one for lgeo.zip.
Here is the overview of all archive.org snapshots of it:

I’m willing to host this on the LDraw servers but someone need to contact Lutz for permission.

the trouble is that already starting from that version
a tree of modifications has evolved, see
https://wiki.ldraw.org/wiki/LGEO

however, of course, archiving the original is maybe still a good idea.

I found a GitHub repo here:

https://github.com/jncraton/lgeo

The license.txt is as follows:

Code:
(c) 1997 - 2018 Lutz Uhlmann

The LGEO library is a fan created collection of definitions for LEGO Geometrical Equivalent Objects (called parts from here on) to be used with POV-Ray. It is no way related or sponsored by
the LEGO Group and free of charge. It may be redistributed freely while copyright of the
intellectual property remains with the author. The LEGO logo displayed on the studs is under
copyright of the LEGO Group.

Maybe Damien or someone could contact the developer and get write access to update it with new parts?
