Fonts and Math
summary
Explains how fonts get generated from math not manual outlines: a nib‑based Metafont model produces strokes defined by equations (Computer Modern is a 60‑parameter family and the only widely used Metafont), an Euler spiral (the Spiro curve) joins lines and arcs smoothly and is implemented in libspiro and in FontForge/Inkscape, and a browser‑based constrained optimizer was built to minimize curvature for shapes like an S (it works but runs ~1000× slower than Spiro).
