mesh_process op• Data kinds: mesh → mesh
• Call: import fullseye as fs; fs.ledger.taubin_smooth(mesh: 'Sequence', iters: 'int' = 10, lam: 'float' = 0.33, mu: 'float' = -0.34) -> 'Mesh' (to call the implementation directly, import mesh_smooth; mesh_smooth.taubin_smooth(mesh: 'Sequence', iters: 'int' = 10, lam: 'float' = 0.33, mu: 'float' = -0.34) -> 'Mesh'; from the registry, ops3d.get("taubin_smooth"))
Non-shrinking smoothing by the Taubin λ|μ filter. → (verts, faces).
> The detailed description below is the original text — the summary and the headings are translated.
各反復で「正の `lam で寄せる段」→「負の mu` で押し戻す段」を続けて掛ける。
`|mu| > lam` とすることで低周波(全体形状)を通し高周波(ノイズ)だけを減衰させる
帯域通過フィルタになり、Laplacian の収縮アーティファクトを打ち消す(球の平均半径が
ほぼ保たれる)。既定 `lam=0.33, mu=-0.34` は Taubin (1995) の推奨に近い。
Args:
mesh: (verts (N,3), faces (M,3)[, ...]) のシーケンス。faces は不変。
iters: λ|μ ペアの反復回数(正の整数)。
lam: 寄せ段の係数、`0 < lam < 1`。
mu: 押し戻し段の係数、`mu < 0 かつ |mu| > lam`(収縮を打ち消す条件)。
Returns:
(verts (N,3) float64, faces (M,3) int64)。faces は入力を保持。
Raises:
ValueError: メッシュ形状不正・面範囲外・iters/lam/mu が不正(fail-closed)。
