aabb — 3D `bounds` op

• Data kinds: points → primitive

• Call: import fullseye as fs; fs.ledger.aabb(points) (to call the implementation directly, import pcseg; pcseg.aabb(points); from the registry, ops3d.get("aabb"))

Usage

Axis-aligned bounding box. Returns `(min (3,), max (3,))`.

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

点群の各軸の最小値と最大値をそのまま返す(`P.min(0), P.max(0)`)。返り値は 2 つの (3,)

float64 配列で、順に `(xmin, ymin, zmin) と (xmax, ymax, zmax)`(軸の並びは入力の列順)。

箱の大きさは `max - min、中心は (min + max) / 2`。単位は座標の単位。

• `points: (N,3) 以外の形状は ValueError、空の点群も ValueError`(fail-closed)。

• NaN を含む点があると `min / max` が NaN になる(非有限の検査はしない)。

用途: voxel 化(`occupancy_grid / points_to_voxel の bounds`)の領域決め、

`obb`(PCA で向きを合わせた箱)との比較。軸に沿わない細長い物体では AABB は大きく余るので、

把持幅の推定には `obb の extents` を使う。
