    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.

Autostereogram Sphere 🌎

I see it! I've been waiting a long time for an autostereogram dweet.
u/Joachim

So cool!! Seems a bit flat for a sphere though :(
u/magna

Works really well!
u/magna

Joachim it could be that your eyes are overlapping slices that are too far away, maybe? Try full screen and getting closer to the screen.
u/magna

KilledByAPixel, do you think you can offset the pixels at a gradient instead of circle slices?
u/Joachim

u/magna Ooh I see it now! :D

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.
