    // \param enable_area_memory : this mode enables the camera to remember its surroundings. This helps correct positional tracking drift, and can be helpful for positioning different cameras relative to one other in space.
    // \param enable_pose_smoothing : this mode enables smooth pose correction for small drift correction.
    // \param set_floor_as_origin : this mode initializes the tracking to be aligned with the floor plane to better position the camera in space.
    // \param set_as_static : this mode defines the camera as static. If true, it will not move in the environment. This allows you to set its position using initial_world_transform.
    // \param enable_imu_fusion : this mode enables or disables IMU fusion. When set to false, only the optical odometry will be used.
