artificial-life op• Data kinds: image → image
• Call: fullseye.apply(img, "alife_wolfram1d", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
*The figure is the actual output on a synthetic 128×128 input. Left: input, right: output. Point clouds are drawn as a top-down scatter (brightness = z), 1-D series as a line plot, volumes as the maximum-intensity projection along z, videos as the middle frame, complex images as magnitude; return values that are not pictures are shown as the values themselves.*
Sweeping knob a (0.1 / 0.5 / 0.9, the other knob at its default):
▸ alife_wolfram1d: knob a sweep (docs site)
Sweeping knob b (0.1 / 0.5 / 0.9, the other knob at its default):
▸ alife_wolfram1d: knob b sweep (docs site)
On other images (synthetic scene / photo / coins. Top row: inputs, bottom row: their outputs. Knobs at default):
▸ alife_wolfram1d: other inputs (docs site)
*The 4th column is a colour (H,W,3) input. This op handles colour without crossing channels (it does not convolve the colour channel as a third spatial axis).*
Wolfram elementary 1-D cellular automaton, drawn as a spacetime diagram.
Reimplements the elementary (radius-1, two-state) cellular automata of
S. Wolfram, Rev. Mod. Phys. 55, 601 (1983) / *A New Kind of Science* (2002).
The initial row is the top row of the image thresholded at 0.5; if that row
is empty a single central seed is used instead, which is the classical
initial condition (rule 90 from a single seed is Pascal's triangle mod 2,
i.e. the Sierpinski gasket). The lattice is circular, one generation is
written per output row, and row 0 is generation 0, so the output is the H x W
{0,1} spacetime diagram.
`a picks the rule from the curated table _ELEMENTARY_RULES`;
`b sets the initial density by adding int(b * W/2)` evenly spaced extra
seed cells to row 0 (b = 0 leaves the thresholded row untouched).

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
The program below has been verified to run (same input as the figure). In Studio's help this block becomes buttons that load and run it on the spot.
