Awesome article.

SDF(or mSDF) isn't the future. It's already "good enough" classic.

This is "the future" or even present as used in Slug and DirectWrite with great performance

Don't forget about implicit curve rendering [0]. The patent will expire soon [1].

I wrote an implementation of the Loop/Blinn paper for Microsoft Game Studios ~20 years ago, I wonder if they're still using it.

Had to do a _lot_ of work to make it production-ready, as their voronoi-based tesselation goes pathological on a lot of Asian glyphs.

I may be remembering totally wrong, but isn't the algorithm used in Slug patented?
