Today's focus was quadratic Bézier curves (3-point Bézier curves). As I said last week, it's more productive for me to study some of these topics offline and share my findings live. Tomorrow, I'll share a write-up summarizing what I've learned about this type of curve. We're a step closer to understanding virtual sketching's code and model architecture.
We saw an overview of Bézier curves and implemented them with the bezierVertex native p5.js function and programmatically, by hand. We managed to draw auxiliary lines to make the creation of Bézier curves easier to understand, animated it to see how to sample points, and exported the resulting animation as GIF, which is a convenient way to share them on social media messaging platforms.
You can spread the word by liking and sharing this tweet.
Thanks for watching.
See you next week!
