Hi everyone,

I'm new to Stage (I mostly work with ROS) and I'm having issues with ranger models.  My final goal is to simulate and visualize sonars (and pass these values into ROS).

My first problem is that I can get Stage to visualize lidar pings but not the ranger scans.  Is this even possible?  (What do 'Ranger ranges' and 'Ranger transducers' mean under View -> Data -> Visualize?)

My second problem is that the Class Reference Page is kinda blank.  Does this mean Rangers haven't been implemented yet?  
http://playerstage.sourceforge.net/doc/Stage-3.2.1/classStg_1_1ModelRanger.html

For example, laser has the GetSamples() function, but I don't see anything for Ranger.

Thanks for your help,
 - Chad
