tb_cutout — 2D typed op

Data kinds: pointspoints

Call: fullseye.apply(img, "tb_cutout", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

Removes a spatial axis-aligned box region and returns `(kept, kept_idx)` (mimicking localized missing data).

> The detailed description below is the original text — the summary and the headings are translated.

既存の点を 1 つ一様サンプルして中心とし、辺長 `extent`(スカラ=立方体, または

`(3,)`=各軸辺長)のボックス内の点をすべて除去する。中心点自身が必ず入るため

最低 1 点は除去される。除去点は必ず辺長 `extent` のボックスに収まる(空間的に

局所的 = ランダム散布とは判別可能)。`kept == points[kept_idx]extent > 0`。

2-D 進化レジストリへ橋渡しした 3d の op `cutout。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。この op に調整点は無く、ab` も使われない。
