I will fill in all I know about the old Open GL/3D that Rudolf did.

I hade a lot of hardware so I could test his work back then.

His work was built using this as references ​http://utah-glx.sourceforge.net/

His old page. ​http://web.archive.org/web/20080510104754/http://web.inter.nl.net/users/be-hold/BeOS/NVdriver/3dnews.html

And currect ​http://be-hold.blogspot.se/2006_01_01_archive.html

Back then 2005-2006 we had another OpenGL Implementation. I think Alexander von Gluck IV rewrote much of it and now we "only" need to implement a Hardware version, same as the software.

I can be wrong about what's need to be done so someone can correct me here :)
