I'm new to Gazebo, and I'm trying to publish what my UserCamera sees as RGB data to a ROS topic. I'm able to setup a new camera object in an SDF with the camera sensor plugin, but I need the UserCamera so that I can make use of its GetVisual function.
I noticed that the newer gazebo versions publish the /user_camera/joypose data, so I thought I'd look at the source for that, but for some reason all of the code for publishing/subscribing there is in UserCameraPrivate.cc, which I can't access.
So far I've basically only gotten simple UserCamera functions to work by making a System plugin.
Definitely trying to climb a steep learning curve here, so any help is greatly appreciated!
