geodesic_mesh — 3D geodesic op

• Data kinds: mesh → signal

• Call: import geodesic3d; geodesic3d.geodesic_mesh(vertices: numpy.ndarray, faces: numpy.ndarray, source: int) -> numpy.ndarray (or ops3d.get("geodesic_mesh"))

Usage

Geodesic distance from a source to each vertex by Dijkstra on the triangle mesh's edge graph. → (V,) float.

References (sample data, literature)

• 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)

• pcl_geodesic — py -3.11 examples_3d/pcl_geodesic.py

Ops the type connects to (they accept signal as input)
