vol_bounding_box — 3D domain op

資料種類:voxelprimitive

呼叫: import fullseye as fs; fs.ledger.vol_bounding_box(domain, margin=0)(要直接呼叫實作,import volops; volops.vol_bounding_box(domain, margin=0);從台帳取用則 ops3d.get("vol_bounding_box"))

Returns `(z0, y0, x0, z1, y1, x1)` with exclusive upper bounds, i.e.

`vol[z0:z1, y0:y1, x0:x1]` is the smallest sub-volume containing every

foreground voxel. *margin* (an int `>= 0`) grows the box by that many

voxels per side, clipped to the volume — headroom for operators with a

spatial footprint (a Gaussian of sigma s needs ~`3*s` voxels of context).

A non-`{0, 1} input is thresholded at > 0.5`.

An empty mask raises `ValueError` (fail-closed): there is no box, and

silently returning the full volume would defeat the point of cropping.
