vol_rotate — 3D geom_transform op

数据种类:voxelvoxel

调用: import fullseye as fs; fs.ledger.vol_rotate(vol, angle_deg, axes=(1, 2), order=1, reshape=False, mode='constant', cval=0.0)(要直接调用实现,import volxform; volxform.vol_rotate(vol, angle_deg, axes=(1, 2), order=1, reshape=False, mode='constant', cval=0.0);从台账取用则 ops3d.get("vol_rotate"))

用法

在一对轴张成的平面内旋转体(`scipy.ndimage.rotate`)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

*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*).
