mesh_split_long_edges — 3D resolution op

• データ種: mesh → mesh
• 呼び出し: import fullseye as fs; fs.ledger.mesh_split_long_edges(V, F, max_edge, max_passes=20) (実装を直接呼ぶなら import meshres; meshres.mesh_split_long_edges(V, F, max_edge, max_passes=20)、台帳から引くなら ops3d.get("mesh_split_long_edges"))

使い方

Bisect edges longer than max_edge until none remains — adaptive refinement (mesh).

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.
