mesh_split_long_edges — 3D resolution op

• 資料種類:mesh → mesh

• 呼叫: import fullseye as fs; fs.ledger.mesh_split_long_edges(V, F, max_edge, max_passes=20)(要直接呼叫實作,import meshres; meshres.mesh_split_long_edges(V, F, max_edge, max_passes=20);從台帳取用則 ops3d.get("mesh_split_long_edges"))

用法

把長於 *max_edge* 的邊二分,直到不再有 —— 自適應細化(`mesh`)。

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。

Each pass splits every over-long edge at its midpoint and re-triangulates

each affected face by the number of split edges (1 → 2, 2 → 3, 3 → 4

triangles), so there are never T-junctions and faces that are already fine

are untouched: the refinement lands exactly where the mesh is coarse.

Stops after *max_passes* (`ValueError` if edges still exceed the target

then). Vertex positions are not moved — the shape is preserved exactly.
