See if there's some differences. Though same program does raw rendering, displaylists, vertexarrays and vertexbuffer objects, it is commented well.
I tried your code, but I can't really make it work with my class. :? The problem is that I still get an AV.

I don't understand. How to lock and unlock a VBO?
