fit_box3 — 3D `geometry` op

• Data kinds: points → primitive

• Call: import fullseye as fs; fs.ledger.fit_box3(points) -> 'dict' (to call the implementation directly, import measure3d; measure3d.fit_box3(points) -> 'dict'; from the registry, ops3d.get("fit_box3"))

Usage

Oriented box fit by PCA (fast, noise-tolerant; the same construction as

`pcseg.obb but with the measure`-style dict). Axes are the principal

directions of the point spread; extents come from the projected span. Returns

`center (cd/cr/cc), axes` (3, 3 — unit ROW vectors, depth/row/col

components), sorted half-extents `l1 >= l2 >= l3, full size, volume`,

`corners` (8, 3), and the RMS point-to-box-surface distance. For the true

minimum-volume box use `smallest_box3. Raises ValueError` on < 4 points

or a degenerate (flat) set.
