#### "journal of graphics tools" code repository ####

This is a repository of code developed and some supplemental material for [articles](http://ftp.math.utah.edu/pub/tex/bib/toc/jgraphtools.html) in the [*journal of graphics tools*](https://www.tandfonline.com/loi/ujgt21) (JGT), as of Volume 14 known as the "journal of graphics, gpu, & game tools" and Volume 16 on as the "Journal of Graphics Tools." N.b., this journal's title is normally not capitalized, though Taylor & Francis do so on their web pages.

Here are the articles where we know we don't have the code. There are others where we don't know if the article even had code; the [Wayback Machine](https://web.archive.org/web/20121208215031/http://jgt.akpeters.com/issues/?volume=1) has no page stored for some articles. Please [let me know](mailto:erich@acm.org) if you can provide any code or know who could.
