Vectors & Dot Product • Math for Game Devs [Part 1]

Bézier curves - how do they do?

They're used for animation, text rendering, and all sorts of curved shapes! But how do they actually work? well, like, that's what the video is about, so, watch it to find out etc!!


• Lots of love to
💛 Jazz "queenjazz" Mickle for making the music ❱ https://queenjazz.bandcamp.com/
💙 Grant "3Blue1Brown" Sanderson for pushing me to finally do this ❱ https://youtube.com/3blue1brown
🐦 Pomax for their wonderful writeup on Bézier curves ❱ https://pomax.github.io/bezierinfo
🐈 Thor the cat for.. hanging out.. when I was trying to record audio with no interruptions
🇫🇷 French subtitles by @damqui on Twitter

• How was this video made?
🔨 Created in the Unity game engine
⭕ Using Shapes, my vector graphics plugin ❱ https://u3d.as/1W37
📈 Using Mathfs, my math library ❱ https://github.com/FreyaHolmer/Mathfs
...along with a bunch of hacky, partially broken, procedural animation tools I made specifically for this video

• Did you know that "osculating" isn't pronounced that way?
✅ yes I do now in fact please stop commenting on it ;-; ❱ https://twitter.com/FreyaHolmer/status/1429472399389507591
