    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.

My first dwitter. I reduced the drawn area, but it still runs very slow

A bit of a disappointment. I am going to try to do this with bigger rectangles now.
u/Xen

nicely done! welcome to the dwitter family
u/KilledByAPixel

fillStyle can be slow when called this often (60,000+ times per frame), you can make a faster/smaller version in grayscale by removing the fillStyle and doing this x.fillRect(i,j,1,(z&w)/w)
u/danny@hille.dk

uncompressed using grayscale and some other golfing tricks ->c.width=w=255;for(m=4e4;m--;x.fillRect(i,j,((C(a=Math.atan2(y,k))*w/d+t*w^S(a)*w/d+t*w)&w)/w,1))i=m%w,j=m/w,d=Math.hypot(k=i/w-.5,y=j/w-.3)

u/vain

Is there any way or reference to learn to understand this source and its Path2D datas?
u/deobfuscate

Path2D is very similar to the line function in SVG data. If you made an SVG, added a line function with this data, you would get half of the logo.
u/deobfuscate

https://developer.mozilla.org/en-US/docs/Web…
u/tomxor

Yeah it's just svg path data, there's a bunch of different commands (single letters), followed by a number of numeric parameters. Spaces can be removed in a variety of places making legebility hard which might be confusing here, e.g if there is a sign e.g 1 -1 this can become 1-1, also parameters which are flags do not need delimiters since they always have length of 1, e.g the two flags of the arc command a 2 3 4 0 0 5 6 can become a 2 3 4 00 5 6, also commands do not need delimiters a2 3 4 00 5 6. The other golfing trick for paths is to figure out when relative vs absolute coordinates will result in shorter parameters (A is an arc with absolute coordinates, a is relative to the previous command position), you can alternate between absolute and relative commands.
u/tomxor

When I made this path, I split each command onto new lines, without messing with spacing. Then figured out the shortest possible parameters, and removed all possible spacing as a last step.
u/4ce

u/vain a you see it? you asked about Path2D ... i know good online app where can drawing and explored SVG path : (this not my , this link not be ads, i not know what will been if you open this} https://yqnn.github.io/svg-path-editor/ ~_^⠀GoodLuck!

Harmonic Resonance: A Sine Symphony

u/brad-ellert

I find it pretty impressive to see what it can come up with given just a problem definition and constraints. Of course minor tweaks are required because it's not perfect, but it make something very coherent despite not actual ability to "see" as an LLM.
