If you wan’t to make an axe, then you might want to create some code to load .obj files, because putting the vertex data manually is going to be a pain. Also, this is a trivial problem you are asking. It is clear that you have no idea what this code is doing. I would suggest starting at the basics. Follow this wiki article and learn how to develop games. Also, if you take a look at the lwjgl wiki, you would know that this renders a cube using what looks like a combo of display lists and immediate mode (correct me if I’m wrong).
Anyways, progress through the steps. Go console->2d->3d. Learn useful concepts on the way.
