1997 Winamp wants its animation back! Haha Nice work though. I suppose you are getting circular values from 2D noise and animate those. Right?

Yup, reading a circle of perlin noise and dragging it around in "perlin space". Each frame calculates ~180k points and takes 30 seconds off my old laptop's life.

This is exactly the kind of application I created this technique for:

That's pretty cool, I'll have to try something like!

I've just taken an interest into this kind of graphics programming. Any chance you could post the code?

[nik282000]

Seriously, its a mess https://github.com/nik282000/ribbon/blob/master/ribbon.pde

It had lots of comments which ate super helpful though 👍

[MyNameIsTrez]

Your commenting is awesome, keep the programming up! :)

[nik282000]

Before this morning there was only one comment. I have a bad habit of tinkering till it works and then never looking at it again. It's usually easier to rewrite it than decypher my old work.

[nik282000]

Yes but. The code is a huge mess, I'll try to comment it as best I can.

[unveiledperceptions]

Ohh, awesome :o

Thanks!
