2016-03-09 10:17:10 -0500 asked a question Visualizing ray traces

I'm working on a plugin that creates a more realistic GPS sensor by performing ray traces to satellites and determines if any are blocked by the environment. I've been able to create a plugin that uses a Physics::RayShape to perform the ray traces and detect blockages. I would like to be able to visualize those ray traces in the Gazebo environment similar to how a LIDAR scan is shown. I haven't been able to figure out exactly where the visual representations are created though. Does anyone know the best way to approach this?

Thanks,

David

2013-08-27 08:25:03 -0500 asked a question "Getting remote endpoint failed." on OSX

I've installed Gazebo 1.9.0 using the homebrew formula on OSX (10.8.4). I can run gzserver and then gzclient and use Gazebo with no problem. Running the "gazebo" executable however gives the following error:

I also updated the formula to pull 1.9.1 and reinstalled and still get the same error. Any suggestions on what could be causing this or how to troubleshoot it?

Thanks,

David
