mesh_edge_stats — 3D resolution op

• Data kinds: mesh → table

• Call: import fullseye as fs; fs.ledger.mesh_edge_stats(V, F) (to call the implementation directly, import meshres; meshres.mesh_edge_stats(V, F); from the registry, ops3d.get("mesh_edge_stats"))

Usage

Edge-length and face-area percentiles with non-uniformity ratios (table).

edge / area hold p5 / median / p95 / max / min / mean; edge_nonuniformity = p95/p5 of edge length and area_nonuniformity = p95/p5 of face area (1 = perfectly uniform; the Itokawa 49k model gives 2.8 / 2.7); n_vertices, n_faces, n_edges, bbox_diagonal, boundary_edges (edges with one face — 0 for a closed surface), non_manifold_edges (edges with more than two faces). Use it before adding synthetic detail: if the ratio is far from 1, the detail you add at a fixed wavelength will alias on the coarse part and resolve on the fine part — remesh first (mesh_isotropic_remesh).
