geom_transform op• データ種: voxel → voxel
• 呼び出し: import fullseye as fs; fs.ledger.vol_rotate(vol, angle_deg, axes=(1, 2), order=1, reshape=False, mode='constant', cval=0.0) (実装を直接呼ぶなら import volxform; volxform.vol_rotate(vol, angle_deg, axes=(1, 2), order=1, reshape=False, mode='constant', cval=0.0)、台帳から引くなら ops3d.get("vol_rotate"))
軸ペアの張る平面内でボリュームを回転する(`scipy.ndimage.rotate`)。

*axes* names the rotation plane and must be exactly one of `(0, 1)`
(z-y plane, turning about the x-axis), `(0, 2)` (z-x, about y) or
`(1, 2)` (y-x, about z — the axial-slice rotation; the default). Any
other pair — including a reversed one like `(2, 1)` — raises
`ValueError`, so the direction convention below is never silently
flipped.
Direction (pinned): a positive *angle_deg* rotates **from the first
axis of** *axes* toward the second — the same convention as
`np.rot90. Concretely, `vol_rotate(v, 90, axes=a, reshape=False,
order=0)` equals np.rot90(v, 1, axes=a)` bit-for-bit when the in-plane
shape is square (the test pins this).
`reshape=False` (default) keeps the input shape (in-plane corners that
leave the frame are lost, entering ones are filled with *cval* per *mode*);
`reshape=True` grows the in-plane shape to contain the whole rotated
frame — the grown output is cap-checked against `MAX_VOXELS` *before*
the call. *order* is the spline degree (exact integer 0..5; >1 overshoots
— module notes).
Returns a `(D, H, W)` float64 volume (same shape unless *reshape*).
