• Call: import fullseye as fs; fs.ledger.signal_jp_mesh(*, lens: 'float' = 0.3, n: 'int' = 3, hood: 'bool' = True, state: 'str' = 'off') -> 'dict' (to call the implementation directly, import roadjp; roadjp.signal_jp_mesh(*, lens: 'float' = 0.3, n: 'int' = 3, hood: 'bool' = True, state: 'str' = 'off') -> 'dict'; from the registry, opsdrive.get("signal_jp_mesh"))
Horizontal vehicle signal head (Japanese style). Origin = center of the bottom face of the signal head; the display face points to −x.

箱: 幅 = n·(lens + 0.10) + 0.05(3 灯・300 mm で 1.25 m)、高さ = lens + 0.13(0.43 m)、奥行 0.30 m、濃い灰。レンズ = 半径 lens/2 の円盤(24 分割)を前面より 5 mm 外(−x 側)に置く。並びは −x を向いて見て左から 青・黄・赤 = 青が +y、赤が −y(運転者から見て左から青・黄・赤 — Wikipedia 日本の交通信号機、一次資料で要確認)。n = 2 なら 黄・赤、n = 1 なら 黄(一灯点滅式)。各レンズの上に庇(薄い箱、長さ 0.25 m、hood)。レンズ径は 300 mm(2017 年度から標準 250 mm、どちらも現役)。
返り値 {"V", "F", "color", "label": 3, "lamp_faces": {"green": (f0, f1), ...}, "width", "height", "depth", "lens"}。lamp_faces はこのメッシュ内の面の索引の範囲(世界に足すときは world_add の返す範囲へ平行移動する — driveworld.add_signal と同じ仕組み)。state の灯だけ driveworld._LAMP の色、他は "off" の色。
