    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.

you can drag the h into your bookmark bar (if existent) or side tray (if open) and can then click it anywhere!

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.

3x+1 Unsolved Math Problem https://youtu.be/094y1Z2wpJg

u/rodrigo.siqueira

Paul Erdős said about the Collatz conjecture: "Mathematics may not be ready for such problems." He also offered US$500 for its solution. https://en.wikipedia.org/wiki/Collatz_conjec…
u/New_Core

I tried to visualize something with the Collatz Conjecture a few weeks ago but I didnt come up with anything good.. I bet someone can do some nice stuff with it here.
u/lewdev

Yeah, I figured there's a way to build out visuals like the ones in the video. I just did a quick one to get started. Math is a great inspiration for dweets.
u/smtsjhr

neat! some more inspiration for visualizing Collats here: https://youtu.be/RzQE2Q7lsT4
