smallest_box3_axis — 3D geometry op

• Data kinds: points → primitive

• Call: import fullseye as fs; fs.ledger.smallest_box3_axis(points) -> 'dict' (to call the implementation directly, import measure3d; measure3d.smallest_box3_axis(points) -> 'dict'; from the registry, ops3d.get("smallest_box3_axis"))

Usage

Axis-aligned bounding box (the 3-D `smallest_rectangle1`). Returns the

`min / max corners and center in (depth, row, col)`, the full

`size (depth, row, col edge lengths), and the enclosed volume`. This is

the honest null baseline that `smallest_box3` beats on any rotated object.

Raises `ValueError` on empty input.

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• oriented_bounding_box — py -3.11 examples_3d/oriented_bounding_box.py
