I use SDFs on my render engine to render text. It allows me to debug values inside shaders. (I can print value of an uniform, texture value etc.)

(It's a combination of line segments for each letter and digit)

Are you aware of Valve's paper[0] for glyph rendering via SDFs? You can get amazing results from a low res glyph atlas.

From what I understand, that paper was extremely influential and the technique has been widely adopted.
