cylinder_unwrap — 3D `curvilinear` op

• Data kinds: voxel → voxel

• Call: import match3d; match3d.cylinder_unwrap(vol, center=None, r_in=0.0, r_out=None, ntheta=180, nr=32, device='cpu') (or ops3d.get("cylinder_unwrap"))

• GPU: this op has a GPU path (device="cuda")

Usage

Unwrap the cylindrical surface of a voxel volume into (height × θ × r) — for inspecting the inner and outer walls of cylindrical parts and pipes. The axis is z (the D axis).

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

Runnable examples (verified samples that actually call this op)

• curvilinear_proj — py -3.11 examples_3d/curvilinear_proj.py
