sun_vector — DRIVE `env` op

• Data kinds: scalar × scalar → any

• Call: import fullseye as fs; fs.ledger.sun_vector(elevation: 'float', azimuth: 'float', north_yaw: 'float' = 90.0) -> 'np.ndarray' (to call the implementation directly, import driveenv; driveenv.sun_vector(elevation: 'float', azimuth: 'float', north_yaw: 'float' = 90.0) -> 'np.ndarray'; from the registry, opsdrive.get("sun_vector"))

Usage

Unit vector in the direction of the sun (world frame, pointing from the ground toward the sun).

north_yaw = 世界の +x から反時計回りに測った北の向き [度] (既定 90° = +y が北、+x が東)。方位は北から時計回り。
