    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.

endless urbanscape

u/zanella

Replace v with v%1080 in the fillRect call and it will redraw itself over and over again. ;)
u/DataMeta

Not sure what you mean - it already re-draws. Hence the 'endless' :P
u/zanella

Weird, the first time I saw this it didn't redraw itself - it seemed to stop once the scanline hit the bottom of the canvas. Didn't notice that it already had a %1080. So yeah, my comment is pretty useless. :)

i have been trying to implement this on my project please help me, thanks
u/DataMeta

You're more than welcome to mess around with this code. What exactly do you want help with?

a bit golfed version.. p=3.14;j=(t*1920)/p;z=Math.random;r=z();m=z();x.fillStyle=R(T(t)*192,96/m,96/r,.9);x.fillRect(-j%1920+1680,j%1080-8,250,64)

Thanks! I was meaning to check how to declare functions in javascript... Although I find that at least 3.146 is needed to closely replicate pi, so ill usually take the 3 extra chars

ok nice dweet though
