int gazebo::sensors::GpuRaySensor::GetFiducial ( int _index) const

Get detected fiducial value for a ray.

    Warning: If you are accessing all the ray data in a loop
    it's possible that the Ray will update in the middle of
    your access loop. This means some data will come from one
    scan, and some from another scan. You can solve this
    problem by using SetActive(false) <your accessor loop>
    SetActive(true).

Parameters

[in] _index Index of specific ray

Returns: Fiducial value of ray
