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]_indexIndex of specific ray
Returns
Fiducial value of ray
double gazebo::sensors::GpuRaySensor::GetHorzFOV ( ) const
