Coordinate Systems

  • Scene Coordinate

    • axis (m): [x, y, z]
    • phi (deg): angle on x-y plane. Positive x-axis is 0 deg, positive y-axis is 90 deg
    • theta (deg): angle on z-x plane. Positive z-axis is 0 deg, x-y plane is 90 deg
    • azimuth (deg): azimuth -90 ~ 90 deg equal to phi -90 ~ 90 deg
    • elevation (deg): elevation -90 ~ 90 deg equal to theta 180 ~ 0 deg
  • Object’s Local Coordinate

    • axis (m): [x, y, z]
    • yaw (deg): rotation along z-axis. Positive yaw rotates object from positive x-axis to positive y-axis
    • pitch (deg): rotation along y-axis. Positive pitch rotates object from positive x-axis to positive z-axis
    • roll (deg): rotation along x-axis. Positive roll rotates object from positive z-axis to negative y-axis
    • origin (m): [x, y, z]
    • rotation (deg): [yaw, pitch, roll]
    • rotation (deg/s): rate [yaw rate, pitch rate, roll rate]
