jMAVSim without GUI #59

Closed GregoireH closed 4 years ago

GregoireH commented 7 years ago

Hello,

Thanks to this post: http://discuss.px4.io/t/lightweight-or-command-line-sitl-simulation-options/2285 Modifying Visualizer3D.java3, and change setVisible(true) to setVisible(false).

I could run SITL using jMAVSim without the GUI as my low computational power computer was having troubles running it properly.

Do you know if most of PX4 users are using the graphics ? Or if most of us are just wasting CPU with jMAVSim fency graphics...

I was wondering if we could set a parameter for this in order to be able to specify that we want to turn off graphics, without having to edit and compile jMAVSim . Do you think it could be feasible and that some people could benefit from that ?

looking forward hearing from you. Best

Hi, thanks for the note. I think this would be worthwhile to add. Possibly it should be consistent with the HEADLESS=1 mode that you can use for the Gazebo simulation.

julianoes commented 5 years ago

This would still be nice, someday. FYI @JonasVautherin.

JonasVautherin commented 5 years ago

If I remember correctly, I tried that a few months ago. But the fix proposed here was only disabling the graphics rendering and not making it truly headless (somehow it still needed an X server to be running, so I could not run that, say, in a headless docker).

Did this ever get resolved? I would really like to be able to run this in a headless docker.

Thanks!

@ekatzfey No, it did not. We'd happily accept a PR!

Note, FWIW

you can run Gazebo headless: http://dev.px4.io/master/en/simulation/gazebo.html#headless-mode
With lockstep now supported the simulation may still run fairly "heavy" but it is much more reliable on low performance hardware.

I submitted a PR.
