This is a JavaScript port of FLARToolKit, operating on canvas images and video element contents. And hopefully one day on device elements with webcam input.
The license is GPL 3 as was the original library. If you use it in your own scripts, you need to make the unminified unobfuscated source code of your script available and licensed under GPL 3.
All the hard work was done by the ARToolKit/NyARToolKit/FLARToolKit people, a huge thank you to them. This port was quite mechanical, though it has some major JS optimizations and a tracking robustness hack or two. And some uninformed bogus hacks in FLARParam to sort-of make it work on 16:9 video.
See demos/AR_simple_webgl.html for an example of integrating JSARToolKit output with a WebGL program.
I've only tested the ID markers and square detection paths, so you may encounter problems working with custom markers. In which case, filing a bug report on GitHub would be very much appreciated.
