If you have ever wondered how a font is rasterized, look no further. In this video I go into depth about the necessity for font rasterization, the math behind it, and how we convert the math to pixels on the screen. I also go over how 1st and 2nd order Bezier curves work. I talk about how to gain an intuition for Bezier curves, and how to formulize that intuition into Mathematical formulae. I also go over how to test if a point will intersect with a 2nd order Bezier curve. This is my entry into 3Blue1Brown's SoME competition and I hope you enjoy it!
