course_turnaround — DRIVE `course` op

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

• Call: import fullseye as fs; fs.ledger.course_turnaround(width=3.5, bay_width=3.5, depth=5.0, entry=5.0, corner_radius=1.0, arc_pts=16, side='left') (to call the implementation directly, import drivecourse; drivecourse.course_turnaround(width=3.5, bay_width=3.5, depth=5.0, entry=5.0, corner_radius=1.0, arc_pts=16, side='left'); from the registry, opsdrive.get("course_turnaround"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

方向変換コース(T 字): 幅 w の道路(x ∈ [0, 2E + bay_width])の側方中央に車庫(道路沿いの幅 bay_width、

奥行 depth)、車庫口の両側に出入口部 E ずつ。

別表第三の図(3JH00000217784)そのもの: 道路(幅 A)の途中に車庫(幅 B × 奥行 C)が直角に付き、車庫口の両側の

道路が出入口部 D、車庫口の凹頂点 2 つがすみ切り E。図は上向きの道路の右側に車庫があるが、ここでは

`side="left"(+y)を既定にし "right"` で鏡映する。車は道路を進み、後退で車庫に入れ、来た方向へ出る

(exit = (0, 0, π); 反対側へ出るときは配置側で向きを選ぶ)。centerline は道路の軸 → 車庫の軸。

面積 = (2E + bay_width)·w + depth·bay_width + 2r²(1 − π/4)。

規格: A = 3.5, B = 3.5, C = 5, D ≥ 5, E = 1 → `params["regulation"]`。

Raises `ValueError`: 幅・車庫幅・奥行・E が正でない、r < 0、E < r または depth < r(すみ切りが辺に

収まらない)、arc_pts が 1 以上の整数でない、side が left/right でない。
