alife_reaction_bz — 2D artificial-life op

• 数据种类:image → image

• 调用:fullseye.apply(img, "alife_reaction_bz", a=0.5, b=0.5)(2-D 的模型是一张图 + 两个标量旋钮 a,b∈[0,1])

用法

类 Belousov-Zhabotinsky 可激发介质(Greenberg-Hastings 自动机)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

A 3-state excitable lattice -- 0 = rest, 1 = excited, 2 = refractory -- with

the Greenberg-Hastings rule: an excited cell becomes refractory, a refractory

cell relaxes to rest, and a resting cell fires when at least `thr` of its 8

Moore neighbours are excited. Because a refractory cell cannot be re-excited,

excitation cannot back-propagate and the fronts organise into the travelling

waves and rotating spirals of the BZ reaction. The image tertiles set the

initial state (>2/3 excited, 1/3..2/3 refractory, else rest). `a` sets the

excitation threshold thr = 1 + int(3a) neighbours, `b` the step count

1 + int(20b). Returns state/2.
