• Call: import fullseye as fs; fs.ledger.jp_sign_stop_mesh(*, side: 'float' = 0.8, height: 'float' = 2.5, pole_r: 'float' = 0.04) (to call the implementation directly, import drivejapan; drivejapan.jp_sign_stop_mesh(*, side: 'float' = 0.8, height: 'float' = 2.5, pole_r: 'float' = 0.04); from the registry, opsdrive.get("jp_sign_stop_mesh"))
Stop sign (regulatory sign 330-A): an inverted equilateral triangle on a red ground (side length side = 80 cm; border line and lettering white, rim and ground red — Appended Table 2, Remarks 1(3)3(8)) + post. The plate faces +x (toward oncoming cars). The corner rounding (R 5 cm) and the "Tomare" (STOP) lettering (character height 13 cm) are omitted (the lettering is shown by the road marking jp_stop_marking_mesh). Returns (V, F, colors) with face colors.
