mesh_detail_map — 3D `resolution` op

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

使い方

Per-vertex coarseness and detail of a mesh (table).

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.
