mesh_detail_map — 3D `resolution` op

• 資料種類:mesh → table

• 呼叫: import fullseye as fs; fs.ledger.mesh_detail_map(V, F)(要直接呼叫實作,import meshres; meshres.mesh_detail_map(V, F);從台帳取用則 ops3d.get("mesh_detail_map"))

用法

網格逐頂點的粗糙度與細節度(`table`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

`coarseness` (nv,) — mean incident edge length, mapped linearly from the

5th percentile (0) to the 95th (1) and clipped; `edge_length` (nv,) the

raw value. `detail` (nv,) — mean angle (radians) between the normals of

the faces around the vertex divided by the mean incident edge length: a

curvature proxy in 1/unit that is high where the *data* already carries

relief, independent of how densely it is sampled. `relief_weight` (nv,)

= `coarseness × (1 − detail_norm)` — 1 where the mesh is coarse and

smooth (add synthetic detail), 0 where it is fine or already rough — the

weight :func:render3d.mesh_displace_fbm-style steps should multiply

their amplitude by. Also `stats` for each map.
