    摘要: Methods and systems are provided for slewing a light beam axis directly between points on the ground. One method involves determining a first position associated with a beam axis of a lighting arrangement in a Cartesian reference frame based on an initial orientation of the lighting arrangement in a spherical reference frame, determining an adjustment for the lighting arrangement in the Cartesian reference frame in response to a user input, determining an updated position for the beam axis in the Cartesian reference frame based on the first position and the adjustment in the Cartesian reference frame, transforming the updated position for the beam axis in the Cartesian reference frame to an updated orientation of the lighting arrangement in the spherical reference frame, and concurrently commanding actuators associated with the lighting arrangement to slew the lighting arrangement from the initial orientation to the updated orientation in the spherical reference frame.
