    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.

u/pavel

If you declare your vars you can't get this to run reasonably well t||x.fillRect(0,0,w=2e3,w);let j=1,m=x.getImageData(0,0,w,w),g=m.data;for(;j<8e6;j+=48+g[j])g[j]=255-g[j];x.putImageData(m,0,0)
u/pavel

you can** get this to run
u/nburn42

Sweet, thanks
u/nburn42

Your code doesn't grab the data every frame, it didn't even cross my mind to only do it once.
u/joeytwiddle

Or just run it in Firefox ;-)

Trying to play with the raw image data is hard

Show more comments…
u/cshadows

wow!!
u/tomxor

It is hard - shame there isn't a simple buffer to write to
u/nburn42

I wanted to build cellular automata based off raw data, but there is so much overhead involved.
u/nburn42

I'll try anyway.
u/tomxor

What do you mean by raw data? using the frame buffer for state? there are quite a variety of CA implementations here but they are mostly tagged gameoflife regardless of specific rule. I made a larger than life one recently that is capable of >1 radi moore neighborhoods
u/nburn42

I see some of your CA, the are awesome, I'll play around with some of your methods too.

Circuit Diagram

u/tomxor

Nice! most convincing xor sampling #circuit pattern i've seen, lots of ball grid arrays
u/ntsutae

(i-t)^(i+t) is great.
u/rodrigo.siqueira

Change ^ to | and you will see falling Sierpinsky triangles! I mean: (i-t)|(i+t)
u/ntsutae

Yes, I've already tried "|","&". The triangles appeared without the use of recursive call. Dwitter told me bit operation skills. Thank you.

u/tomxor

Wow nice! it's so fast.
u/tomxor

Hah, A lot of variations with comments appended, I found when doing this kinda #fuzzing it can be useful to padd the operators with spaces, you like a few things like power and decrement/increment but also protect loop variables from assignment and stop comments.
