Debug Window doesn't open

[mongrelgem]

When I execute the run command : ./bin/main_on_image ./data/sequence_30
I run into the following issue :

Do you know how i can solve this issue ? Have you run into this before ?
Also , it's not necessary that i have to get a display. Is it possible to try to get the output in a file ? If so , what are the changes i have to make?

Please make sure you ran $./scripts/launch-container-*.sh to have an access to the X11, and try again. (If the container already exists, remove it before executing)
I don't know why it happens but trying multiple times may work.

[mongrelgem]

I am not running it through docker. I have access to the X11 , so I don't think that's the problem

[IshitaTakeshi]

So you built on your ubuntu or somewhere?

[mongrelgem]

Yes Ubuntu 16.04.

[IshitaTakeshi]

That's surprising. I struggled so much to reproduce the environment and that's why I used docker.
But anyway, the core code is brought from the original LSD-SLAM implementation (and the forked repository of other people), and what I did is just reproducing the execution environment, so I don't know why it happens.

[mongrelgem]

Is there any way to disable the display commands and just redirect the output to a file say .ply or xml ?

[IshitaTakeshi]

Maybe it is done here so just to remove it or to set displayDepthMap=false will do what you hope.
I added code that exports point cloud to ply on the refactor branch of this repo. It will require you to resolve some dependencies when building the source so see the Dockerfile after git checkout.
