course_s_curve — 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_s_curve(width=3.5, radius_outer=7.5, arc_fraction=0.375, entry=4.0, arc_pts=48) (to call the implementation directly, import drivecourse; drivecourse.course_s_curve(width=3.5, radius_outer=7.5, arc_fraction=0.375, entry=4.0, arc_pts=48); from the registry, opsdrive.get("course_s_curve"))

Usage

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

曲線コース(S 字): 直線 E → 左弧(中心角 2π·f)→ 右弧(同じ)→ 直線 E。

外径 R_o = `radius_outer`、内径 R_i = R_o − w、中心線の半径 R_c = (R_o + R_i)/2。2 つの弧は共通接線点で

曲率の向きが反転する。多角形は中心線の標本点を法線方向に ±w/2 ずらして作る(弧の標本点は外円・内円の

上に厳密に乗る)。面積 = 2πf(R_o² − R_i²) + 2Ew。規格: A = 3.5, B = 7.5, C = 3/8 → `params["regulation"]`。

Raises `ValueError`: 幅・外径が正でない、R_o ≤ w(内径が 0 以下)、arc_fraction ∉ (0, 1)、E < 0、

arc_pts が 1 以上の整数でない。
