Hello all

I tried to create a laser sensor plugin based on the gazebo::sensors::GpuRaySensor. After lots of head breaking i discovered that this sensor do not support intensity reading. The GpuRaySensor::GetRetro function that suposed to provied the intensity readings in the GpuRaySensor.cc file looks like this :

double GpuRaySensor::GetRetro(int /*_index*/) const
{
  return 0.0;
}

The questions are : why is it so ? Is there a fundamental difficulty in applying GPU for intensity reading, or is there some other reason ? and also, does this capability is planed to be added in the near future ?

Thanks.

Is it somehow possible to still access the answer by Nate?
