@hulaboop It looks like the Docker container does not have permission to show application windows on your screen. Have you given “docker permissions in your X server” with xhost +local:docker?

You’ll need to run the xhost command every time you restart the host. I recommend adding it to your login scripts or to scripts you use to start the sandbox apps.

@marcocspc

You’re welcome. sarndbox-docker is an interesting idea and I’d like to see how much it can help bridge the increasing gap between AR Sandbox’s expected environment and current distributions.

Do you think it makes sense to add a launch script? Maybe a sarndbox-run BASH script that automates running the various Vrui, etc. commands in the container.

Could you also share a photo of your sandbox with room lighting on?

What I find odd is the gentleness of the slope at your box edges, our sandbox has vertical “cliffs” at the sand edges and this is reflected in tight contour lines.

I think the “water” (in lava mode) you are calling a “shader” is part of the “color map” in the sandbox software, it describes the sand elevation using different colors. The default color map is blue below sea level and a rainbow of colors above sea level.

You can tell the running sandbox to use a new color map file:

1) If not already done, add a control pipe in the folder you launch SARndbox. In a terminal window, run mknod SARndbox.pipe p to create a pipe you will use to control the running sandbox.

2) If not already done, tell SARndbox to use a control pipe. This is done with the -cp SARndbox.pipe option. I.e. “SARndbox -uhm” becomes “SARndbox -uhm -cp SARndbox.pipe”. The pipe names must match in steps 1 and 2.

3) Create an alternate color map file. Find “HeightColorMap.cpt” and copy it, in the same folder, to “HeightColorMap-lava.cpt”. The four columns in cpt files are (left to right) elevation, red, green, and blue. Edit “HeightColorMap-lava.cpt” to swap the red and blue values for all elevations below sea level. For example, the first line (“-40.0 0 0 80”) becomes “-40.0 80 0 0”.

4) Test your new color map in a terminal window. Run echo "colorMap HeightColorMap-lava.cpt" > SARndbox.fifo to change to the lava color map. Run echo "colorMap HeightColorMap.cpt" > SARndbox.fifo to change to the default color map.

5) Add echo "colorMap <color map file>" > SARndbox.fifo to the “switch” scripts to match the color map to the texture.

6) Ask questions if you run into problems.

It looks like the simpler fix (if you’ve “done the permissions changes”) is to use ‘$ make build’ rather than ‘$ make’.

Did you run RawKinectViewer with sudo? sudo is needed because the calibration file will be written to a “system” (vs “home”) directory.

What do you get when you run ls -l /usr/local/etc/Vrui-8.0/Kinect-3.10/ in a terminal window? This should list files and permissions in the same directory RawKinectViewer wants to write the calibration.

Thank you for posting about your project. I don’t have much experience with Docker and none with desktop applications in Docker.

Could you give a non-technical explanation of sarndbox-docker?

My own confusion can be seen in two areas:

Is this for building a package? Or will the container run the sandbox software, too?

If I run an Ubuntu 18.04 container, do I need to update and manager software for two systems? One in the container and one on the host?

I suspect you are not using Linux Mint 19, the recommended OS for AR Sandbox. It’s possible to use other OSes, but some changes may be needed for the build process.

Could you post the output of lsb_release -dc? The output will tell me what OS version you are using.
