https://github.com/librarianofbabel/libraryofbabel.info-algo This is the original algorithm released by the site author but admittedly it is for an image version of the library. But I did manage to dig up his email so you could possibly ask him to release the text version of it: firstname.lastname@example.org
I've been in sporadic contact with Jonathan since 2015. I wasn't just loading content from his website without his permission :)
In fact, a very early release of this 3D library used to be hosted on libraryofbabel.info http://libraryofbabel.info/lob3d.html. I'm guessing that it has gotten lost during the recent time of technical difficulties that the site went through (same as with the old forum).
