    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Pendulum Synch - Kuramoto Model

u/Qwerasd

This is really cool.
u/katkip

#math is awesome
u/iverjo

Explanation?
u/rodrigo.siqueira

The Kuramoto Model describes how small interactions between oscillators can lead to synchronization between them. E.g. flashing of fireflies, group of metronomes, neural network of spiking neurons can sync after a period. Oscillatory neural networks are a promising field for future research in both natural and Artificial Intelligence
u/lionleaf

Here's a recent youtube movie that's relevant, and perhaps an inspiration: https://www.youtube.com/watch?v=J4PO7NbdKXg #pendulum

very nice
u/gambit

hi im new! can you explain me "c.width|=0" what does it do? thanks
u/DataMeta

Welcome! It's a shorter way of clearing canvas pixels/state. Can be chained like so: for(c.width|=n=i=256;i--;). It can't be done here because we must clear the canvas before scaling it

u/ivylab

I don't even ... this is so cool, like a forest
u/pavel

This thing ((i&2)-1)*(2+i%7) takes so many characters. If somebody can figure out a shorter way to generate random-ish positive and negative numbers that aren't too close to zero that would be awesome. 7*C(i) is almost perfect but gets close to zero so you'd have trees on the path.
u/pavel

Oh! 3/C(i) works well here, but has no bound which will be an issue in other contexts.
u/KilledByAPixel
