Talk:Quadray coordinates

Why isn’t this just a redirect to barycentric coordinates?
The term “quadray coordinates” is apparently a nonstandard term, only used by a handful of people in self-published works, and I’m not convinced it’s notable for Wikipedia. If this topic must have its own article (there’s already a lot of stuff in the barycentric coordinates article), it seems like it could just as well be retitled “barycentric coordinates relative to a tetrahedron” or similar, or could be incorporated as a section into the Synergetics coordinates article, since Fuller’s ideas are at least somewhat well publicized. In either case, standard mathematical terminology could be used.

The citations here are all mailing list posts. While they might be interesting to someone, and I don’t see any inherent problem with linking to such sources as external links, I don’t think they meet Wikipedia’s standards as reliable sources for supporting this article’s notability or credibility.

The Synergetics coordinates article bears little resemblance to anything published by Fuller. Clifford Nelson came up with this name and attributed his ideas to Fuller without substantiation. As principal author of the Quadray Coordinates page *and* the Synergetics_(Fuller) page, I'm well informed enough to link Quadray Coordinates to Fuller, without following Nelson's strategy of posthumous attribution. The nomenclature Fuller invented is consistently adhered to within the Quadray literature (cite Math Forum link) which is why this page connects strongly to published works by this well-known author (with whom I had correspondence, cite RBF Stanford Archive). Plain vanilla barycentric coordinates do not share this advantage.

The NCTM purchased Math Forum after mathforum.org severed ties with Drexel U, however as of October 2018 mathforum.org appears to be permanently down. I'm redirecting the link to Quadray Papers at Math Forum to a memorial page within Archive.org which, in turn, still links to a live website where more information is to be had. If mathforum.org resurfaces, I'll happily switch the link back. I'm also adding a link to a contemporary Jupyter Notebook following standard citation format for such media.

New version of Math Forum includes redirects that keep old URLs working, Switching external link back, happily. Kirbyurner (talk) 23:00, 7 November 2018 (UTC)
