Once you’ve implemented the Lorenzetto et al. algorithm for polygon tessellation, it’s pretty clear it’s the best one.
It’s similar to the GLU tessellator, but it’s *so* much simpler. When floating point error is your nemesis, simpler is usually better.

I tried implementing Unum's here github.com/jrmuizel/pyunum. Regular Unums are more comparable to interval arithmetic and have similar problems. I haven't looked at the subsequent formats as much, but overall I think the proposals need a lot more baking before use.
