Hi Wiebe,
In order to work on OpenG, you'd be expected to know how to use subversion and the issue tracking system on SourceForge. Also, you'd need to be committed to producing software of very high-quality and working with others on the OpenG team. We don't have a tutorial, but we have been documenting
our process in the
OpenG wiki. Probably the best first step is to find out who is interested in working on such a tool -- you should post to the
OpenG Discussion Forums. Also, it would be good to show people what you currently have developed.
Thanks,
-Jim
