    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

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.
