I'm under the impression, maybe wrongly so, that every other week we saw a primer on some basic CG stuff: Bézier curves, Fourier transforms, Dithering, Tonemapping, ..etc, of themes being fetched from a pool of maybe 10 items that cycle every once in a while but get upvoted because CG stuffs are inherently cool (and they're often well written like this one). I think I'm gonna make `primersprimer.graphics` to list the…

Maybe your impression also has something to do with this being the 20th repost of the same link.

A very simple explanation of Bézier curves is this:

- You have one polynomial describing the x-coordinate and one describing the y-coordinate, and both polynomials have the same degree (two for quadratic, three for cubic Bézier curves)

- The two polynomials share the same parameter t, which runs from 0 to 1.

That's all.

In its defense, this is also happens to be a really good link, and every time it gets posted, new people encounter it for the first time. (And I'm always happy to see it once more).

The cynic would say primers on basic stuff are easy to create even if you're not really any sort of expert in the area, so people create a lot of them and lots of people who also aren't expert think that's great.

This, however, is pretty damn nifty, esp relative to most 'let me explain to you with prettier pictures what google (now chatgpt) just explained to me' fluff.

have been a graphic designer for the last 15 years, never know how complex a simple bezier curve is. solid resource.

Often in mathematics (and by extension most science I guess), when something is named after someone, it usually means there's a huge amount going on behind the scenes if you start looking.
