Actually it's not hard, but possibly a bit counter-productive - the
solution is to find a non-indexed 3D file format. The problems with obj
are compounded by the fact that they support multiple indices for
position, normal, texture etc, whereas OpenGL only supports one for all.

So there is quite a lot of processing going on, and added complexity.
