perpetual op• Data kinds: none → rgb (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.perpetual_chaos_game(points: 'int' = 400000, size: 'int' = 520, seed: 'int' = 0, vertices: 'int' = 3, ratio: 'float' = 0.5, sub: 'int' = 2) -> 'np.ndarray' (to call the implementation directly, import perpetual; perpetual.perpetual_chaos_game(points: 'int' = 400000, size: 'int' = 520, seed: 'int' = 0, vertices: 'int' = 3, ratio: 'float' = 0.5, sub: 'int' = 2) -> 'np.ndarray'; from the registry, opsgenerative.get("perpetual_chaos_game"))

カオスゲーム ―― 賽を振って半分ずつ寄るだけで、シェルピンスキーが出る。
不変量: 3 頂点・比 1/2 の吸引子の箱数次元は log3/log2 = 1.5850。
★描き方が測れる真値を変える。同じ点列でも、切り捨てて積んだ絵から測った
次元は真値から −0.032 ずれるのに、双一次 + asinh で描くと −0.0030
—— 10 倍正確になる(しきい値 0.1、実測)。濃淡は飾りではない。
