OK - now you've made it clear that this request is linked to the hirstarts
"project" I see the context of your question - which alters my response
somewhat.
You're free to develop non-Lego parts and primitives which can be rendered with
the LDraw tools, but if its outside of the LDraw library, then I think its up
to you to set your own standards and definitions. In basic terms, primitives
are nothing special - just a bunch of files in another directory in which the
LDraw tools are pre-configured to search.
Representing texture in LDraw .dat files is not easy, and whilst you won't need
a Maths qualification, it will help - if you want to go down that route.
You _may_ get some help here, but the focus of interest here is likely to be in
CAD for Lego parts, I'm afraid to say. Personally, whilst I admire the concept
of the self-moulded parts, I don't own any of these moulds, some am unlikely to
be able to make any meaningful contribution to interpreting them as .dat files.
One rule we do try to make is that part authors must have the physical part to
hand in order to accurately model it.
I suspect that most of the LDraw part authors have more than enough Lego parts
to keep them busy - I certainly do. Partly because we've done all the easy
parts - so what's left takes longer per part, partly because there's always new
parts appearing.

Now I understand the context of your question I'd like to clarify this offer,
which was only made in the context of Lego LDraw primitives - of which there is
still some scope for development.

Yes, documentation is always good, and is being improved all the time, but I
wouldn't place this very high on a priority list. We seem to be able to cope
pretty well in assessing new primitive development with the collective
experience of a few long-standing contributors.

Sorry if this sounds downbeat. I do wish you luck with this project, and look
forward to seeing the first instructions generated with the LDraw tools, but I
don't have the time to assist with such a divergent project at this time.
