    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.

#LargerThanLife #Automata Bugs Rule

Show more comments…
u/tomxor

The Larger Than Life "Bugs" rule R5,C0,M1,S34..58,B34..45,NM. You can introduce more entropy by adding spaces to the code (to restart) which causes i&1 to be combined with existing state in the rule's dead space.
u/tomxor

This uses a sliding window to efficiently compute the sum of arbitrary radi Moore neighbourhoods (i.e box blur kernels). It naturally wraps to the next line giving it a kind of twisted toroidal space, which takes less code and is more efficient since it is only necessary to initialise the sliding window once per dimension: O(2n+2r). The FPS is half of what is displayed since every other frame is used to sum the transposed sum of x.
u/tomxor

Other sized w must be a power of 2 and i must be at least w**2+r+1 (r=neighbourhood radius) to allow the sliding window to correctly initialise, otherwise a bad sum will propagate throughout the grid usually causing everything to die.
u/KilledByAPixel

👍 Thanks for the explanation!
u/tomxor

hmm the larger than necessary i seems to be introducing artifacts... change to i=w*w+6 if you want to see the pure rule.
u/katkip

Woow! I remember it from the The Powder Toy game

The Dweet below this one is super slow and it is slowing down this simple one. Doesn't seem fair to this dweet.
u/DaSpider

Try reducing your browser's window, or moving to portrait mode on mobile, allowing only one dweet per page.

Everybody will have the same issue so this dweet might get less Awesomes than if it was posted next to different Dweets.

Perhaps with enough comments the following dweet wont be activated.

Underwater lava cave #perspective

u/tomxor

I keep switching perception between cave and mountain top, it gets stuck on mountain top... i can't control it 😳
u/sigveseb

I don't see mountain top 🤔 how?!
u/tomxor

funny, i can't see anything else now... it;s like looking down from above a mountain peak. Maybe imagine you are looking down from a circling helicopter.
u/rodrigo.siqueira

This #illusion is called "bistable perception". When I posted it was looking like a cave, now it seems to keep changing between mountain top and cave. I prefer a cave.
u/sigveseb

yes, I see it now!
u/rodrigo.siqueira

To see the mountaintop, maybe look at the blue and imagine it is the floor or the sea, far away.
