mesh_edge_lengths — 3D terrain op

• Data kinds: mesh → signal

• Call: import render3d; render3d.mesh_edge_lengths(V, F, *, per: 'str' = 'vertex') -> 'np.ndarray' (or ops3d.get("mesh_edge_lengths"))

Usage

Local edge length of a triangle mesh → `(N,)` per vertex (mean of incident edges),

• 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.

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