read_3mf — PRINTPATH format op

• Data kinds: text → mesh

• Call: import fullseye as fs; fs.ledger.read_3mf(path: 'str') -> 'tuple[np.ndarray, np.ndarray]' (to call the implementation directly, import printpath; printpath.read_3mf(path: 'str') -> 'tuple[np.ndarray, np.ndarray]'; from the registry, opsprintpath.get("read_3mf"))

Usage

Reads 3MF (3D/3dmodel.model inside the zip, 3MF Core Specification) into a triangle mesh mesh = (V, F).

Multiple <object> elements are merged into 1 mesh by concatenating vertices (the transform matrix of <build> applies the 3×4 transform). The unit is <model unit> (default millimeter; inch / centimeter / meter / micron are converted to mm).

• 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.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
