Neat! I don't often see text-rendering algorithms I didn't try myself. I implemented several at my startup. This wouldn't have saved me because I needed resolution independence, and anti-aliasing. Also it might not generalize to all bezier curve font files. Converting curves to pixels can be hard, especially when glyphs cross over themselves. In general, it feels like standard text rendering is solved, and non-standard use-cases are brutal to attempt.

This actually seems conceptually similar to my favorite method by Will Dobbie (but much simpler). Both take raw font data and use it directly on a shader. The difference being, this method takes pixel data and stores it in arrays. Will takes svg path data and stores them as a "vector texture"

He made a cool demo, if anyone is curious: https://wdobbie.com/warandpeace/
