vol_uncrop — 3D domain op

Data kinds: voxelvoxel

Call: import fullseye as fs; fs.ledger.vol_uncrop(part, offset, shape, fill=0.0) (to call the implementation directly, import volops; volops.vol_uncrop(part, offset, shape, fill=0.0); from the registry, ops3d.get("vol_uncrop"))

Usage

Paste a cropped sub-volume back into the full frame (inverse of

:func:vol_crop_domain).

*part* is placed at voxel *offset* `(z0, y0, x0)` inside a new

`(D, H, W)` float64 volume of the given *shape*, everything else set to

*fill* (the 2-D `full_domain` restoration, made explicit — the cropped

result must land at exactly the coordinates it came from). The part must fit

entirely inside *shape* at *offset*; anything else raises `ValueError`

rather than silently clipping data. *offset* and *shape* must be whole

voxel counts (a fractional value is rejected, never truncated — a silent

`int(1.5) -> 1` would shift the data one voxel with no warning), and

*fill* must be a finite number: every operator in this module refuses

NaN/Inf voxels, so a non-finite fill would produce a volume nothing

downstream will accept.
