mesh_edge_stats — 3D `resolution` op

• 数据种类:mesh → table

• 调用: import fullseye as fs; fs.ledger.mesh_edge_stats(V, F)(要直接调用实现,import meshres; meshres.mesh_edge_stats(V, F);从台账取用则 ops3d.get("mesh_edge_stats"))

用法

边长与面面积的分位数,以及不均匀比(`table`)。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

`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 (:func:mesh_isotropic_remesh).
