jp_pole_mesh — DRIVE japan op

• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.jp_pole_mesh(*, height: 'float' = 10.0, r: 'float' = 0.17) (to call the implementation directly, import drivejapan; drivejapan.jp_pole_mesh(*, height: 'float' = 10.0, r: 'float' = 0.17); from the registry, opsdrive.get("jp_pole_mesh"))

Usage

Builds the triangle mesh of a Japanese utility pole (concrete pole + crossarm).

Returns (V, F, colors): vertices (n, 3) [m], faces (m, 3), per-face colours (m, 3) (0..1). The pole is a cylinder of radius r [m] and height height [m] (z up, foot at the origin); the crossarm runs sideways for 1.8 m, 1 m below the top.
