    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.

An animation showing the impact of resolution and loop depth on the quality of a mandelbrot!

Show more comments…
u/Blacklink

I think that I 'may' have been able to make it draw the pattern without compression but to make it more unique I wanted to add these features which required compression
u/Blacklink

the resolution changes but also the max resolution increases over time, just as the loop depth increases over time
u/Xen

woah! that is damn impressive! i love it

Circle Wave #beesandbombs 🐝 💣

u/KilledByAPixel

This one was fun because I found a way to combine the loops and hide the start/end gap that removes the need for a beginPath. Freeded up enough space for background color, or something cool in a remix.
u/aleamb

yeah!
u/pavel

Buggy in Safari. Jagged things sticking out, i think from the line end-caps, also breaks after a while because you didn't wrap-around the angle in arc.
u/pavel

Huh, actually both issues are resolved by modding the arc angle by 2*pi

harmonic wave equation (in javascript notation y=(x,y)=>A*S(2*Math.PI*(t/T-x/λ))) - move mouse to change wave length and amplitude (period is fixed at T=1 for simplicity)

u/username

u/marc8 I guess we had the same idea. However, my intention was to show a harmonic wave equation using d/14535 and then I just remixed that
u/username

actually, d/14535 does not do that. I did not post the dweet I had originally drafted. it used the above equation (in my very first comment) in code and that is exactly like that
