    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.

I see that this is using the traditional Sumi-e techniques (ancient oriental black ink painting) with the correct use of brush strokes, bamboo composition and harmony. #nature

One trick here is f();g();h(-1,-1) is the same as h(~f(),~g()) when f and g return a falsy value, undefined in this case.
u/pavel

Notice how none of the distance variables are based on time, only angles are, yet the distances are changing and nothing is rotating...
u/pavel

Try making the moving a little faster :)

After I wrote this I looked for other dweets using a similar technique and this is the earliest one I've found, and it includes an explanation d/10212
u/KilledByAPixel

Amazing work! I have not seen the ~ before, will be using it a lot now. I tried to explain the 60*t trick in one of my blog posts, https://frankforce.com/?p=7160
u/pavel

That is an amazingly detailed explanation with great visual aids.
u/pavel

To clarify your explanation, any integer time works. 60*t is naturally an integer (ish). frame is one char longer without numerical errors. In general, (n*t|0) works for any n.

Torus at the Discoteque

u/rodrigo.siqueira

I am inside a #torus. It reminds your previous #d3 https://www.dwitter.net/d/8707 and also this rotator https://www.dwitter.net/d/13254

I did this from scratch and managed to implement a torus in much smaller space than last time. Notice the little ghost effect trick. There's still 22 bytes left but I felt the demo was ready.

#interactive #calligraphy #paint #brush #particles

u/tomxor

The brush pressure is derived from velocity and direction (so more caligraphic)
u/BriSeven

I love how it feels simultaneously precise and digital and messy analogue.
u/tomxor

Thanks :) The dynamics can be easily tweaked too, A*.7 and B*.7 are the inertia (could interpret as how articulated the brush is) and (C-X)/9 and (S-Y)/9 are distance based attraction to pointer (could interpret as bristle length maybe?)

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
