    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.

DTV #Default

u/KilledByAPixel

From back when DTV used to show actual dweets and not just reality garbage
u/KilledByAPixel

Remember dweetis and dweethead? That was a good show.

This dweet was actually directed by Martin Scorsese who went on to win the best default at the DTV awards in 1988

Color #zoom #julia #fractal using "X<i"

u/tomxor

For zoom without slowing down use k=t**t, but you will need very precise coordinates. Here are some other coords I found: f((X-50+k)/k+5100096e-9,1-(Y-28+k)/k), f((X-50+k)/k-2,1-(Y-28+k)/k+201113e-7)

Oops, hitting subpixel rendering differences again... intended for firefox, chrome looks a bit too mushy, change fill pixel to .3 for chrome.
u/joeytwiddle

Pretty nice! 😻
u/13thptr

amazing
u/tomxor

Due to subpixel rendering differences, for Chrome: see d/18346
u/Joachim

Wow! #underrated #colourful How did you make it infinite? Whenever I’ve tried making a Mandelbrot it always pixelates after the first few seconds of zoom ing in.

#julia set for c = −0.8 + 0.156i

u/pavel

Using x*y<n instead of the normal n&&x*x+y*y<2 is much shorter and creates the black whisps that look pretty cool.

This version makes it easy to play with different values of c. You can find some in https://en.wikipedia.org/wiki/Julia_set#Quad…

(X=-0.7453, Y=0.1127, R=6.5e-4) section of the #mandelbrot set

u/pavel

This version draws 1x3 pixels to speed up rendering. for(let i=2e3,f=(x,n=420,a=0,b=0)=>a*a+b*b<n?f(x,n-1,a*a-b*b+x,2*a*b+.1133-t/13845):n/420;i--;)x.fillRect(i,60*t,s=f(i/8e5-.7467),s) looks better in fullscreen but is 3x as slow.
u/pavel

let and the automatic scoping of args in f makes this _really_ quick. I can increase the loop to 4e3 iterations and still have 60fps on my machine. Would be interesting to speed this up by rendering multiple rows per frame.
