None-patented Triangle library alternative?

Hello Everyone,

I was happily using Zach’s awesome ofxTriangle addon for a mobile app scheduled to launch in a month or two. But then to my horror, I forgot that Triangle is actually patented. That’s a big no for a struggling indie dev like me, at least for now.

So, is there any free Triangle alternative out there I can use?

Thank you very much in advance. I’ll appreciate any guidance you can point me to.
