vol_bounding_box — 3D domain op

• データ種: voxel → primitive
• 呼び出し: import fullseye as fs; fs.ledger.vol_bounding_box(domain, margin=0) (実装を直接呼ぶなら import volops; volops.vol_bounding_box(domain, margin=0)、台帳から引くなら ops3d.get("vol_bounding_box"))

使い方

Tight axis-aligned bounding box of a mask’s foreground, in voxel indices.

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.
