2d visibility ⚓

I have written a Haxe implementation of this algorithm, open source under the Apache v2 license (similar to MIT and BSD, it can be used in commercial projects). Haxe code can be compiled into Javascript, Actionscript, C++, Java, C#, or PHP. I compiled it into Javascript for this web page and compiled it into Flash for some of my other projects.

Apart from that being a great article the demos are all live and all look gorgeous the Mac Book Pro Retina Display. Might be worth looking into Haxe.
