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