my configuration below can run most of the worlds in gazebo with a roughly
30 fps. but for the stereocamera.world, it only shows 2 FPS and it is too
slow to move the scene around using mouse (even get stuck).
btw, i am now working on simulating a mobile robot with stereocamera, but i
did not find many materials helping start with it. even the documentations
on the website seem not up to date. could anyone give some insights on how
to start with stereocamera simulation?
