Yes - I think the spec is ridiculous. I wasn't meaning to suggest that we
should try to implement the whole spec.

Yeah, just looking at your code, I think we more or less implemented the
same features. The two reasons I decided not to throw mine away and hack on
yours was:
1. I don't think triangulation should be the role of the importer - though
kudos for actually implementing this :)
2. I think the parser should be decoupled from the view layer because:
A. You can rewrite/replace your drawable Mesh object etc. independent of
the parser
B. You might want to other things with the mesh - smoothing etc.
3. I'm lazy and my obj parser was already working for my needs.
I think some improvements could be made to mine:
1. Optional filters for post-processing - for example: triangulation as you
implemented
2. Support a few more "reasonable" features of the Wavefront spec.
Would you be interested in collaborating on this? And to Alex - if we
arrive at something sufficiently abstract and useful in any pyglet
application, would you be interested in putting this in pyglet core? I
imagine this would entail more work - e.g. a Mesh class in pyglet. If
there's not sufficient interest in the community, then I definitely don't
want to waste any effort.
Cheers,
