    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.

why tild before x ? ~x ?
u/tomxor

all of the x.method() calls return undefined, and bitwise operators coerce any non-number into 0, so ~x.foo() = ~undefined = ~0 = -1. The purpose of this - all of those method calls are defined as parameters to other methods, not for their return value, but to save 1 char. i.e x.foo(0,0);x.bar()=18 x.foo(0,~x.bar())=17, that the parameter is -1 instead of 0 doesn't matter too much in these cases.

u/OscAV Hello! Do you mean the squares in the code? They come from a fancy tool that can shrink long dweets. See d/14282

d/31930

u/aaaaaz

anylink to understand how does it works ? it looks like Lissajous but superposed
u/taupelink

No links handy, sorry! I can say that this code adapts the concept of signed distance functions. f is a SDF in one dimension, g in two dimensions. g uses binary arithmetic to kind of pick out certain parts of the output of f, and the parameter of g makes it work at different scales.
u/taupelink

Also: If you see a term like "i%2" or "i%3" or "(i&5)" in any of my recent dweets...that tends to superimpose two related-but-different patterns on each other. Which can be hard to make work. I am still experimenting!
u/taupelink

*two or more, depending on the expression
