I’ll try breaking my reply into smaller bits to see which parts are rejected. If you need help getting any of these to work, please don’t hesitate to ask.
Let’s begin…
There are two (and a half) official interfaces for removing rainwater: the -evr command line argument and configuring a Vrui tool to “Manage Water”.

It’s hard to put dates on releases for the Kinect package, but it looks like this was changed in 2015 for v3.2.
Was your previous sandbox running SARndbox v1.6? Or had you used a 2.x version before mothballing?
Thank you for the video. I estimate your full disk has a diameter of about 15.25 cm.
The target disk needs to be close to CD/DVD size (12 cm diameter) before the DiskExtractor will mark it as a valid target. If I’m reading the code right, any diameter between 10.9 cm and 13.2 cm should work.
I suspect your target disk is too large. Try trimming the paper part of your disk to CD/DVD size.
Welcome to Linux and this forum.
Yes, the AR Sandbox will work with Ubuntu. Linux Mint (LM) is Ubuntu with additions and tweaks. The AR Sandbox software will work with most distributions of Linux.
You IT department might not like that the sandbox has not been updated to work on more recent versions of LM or Ubuntu. Your options are to use Ubuntu 18.04 (LM 19.3) as the currently recommended OS or use a newer version of Ubuntu (i.e. 22.05) and account for the differences.
One approach for a newer OS, as lead by @solanic, is to update the
Build-Ubunutu.shscript. A second approach created by @marcocspc, is to run the sandbox in a container.Do you think it would be worth trying to switch to Linux Mint?
Yes, but… There are tradeoffs with each option.
Linux Mint 19 is the AR Sandbox supported version, but it may not work on newer hardware.
Linux Mint 21 will work on more computers, but the sandbox software build process is slightly different.
sarndbox-docker seeks a middle way by containing the sandbox software in a virtual space within a more recent Linux verison. But, it is a newer solution with few people testing it.
Did you run
xhost +local:dockeragain? This will need to be run after every login and before any of the docker-compose commands.I tested sarndbox-docker and I get the same error you shared. I see the error in Wayland and Xlib modes until I run the above xhost command. After the command,
RawKinectViewerwill show me both camera feeds from the Kinect.@marcocspc Does the host (Ubuntu 22.04) need to use Xorg for sarndbox-docker to work? The default display server looks to be Wayland.
Congratulations. That was good thinking. If you have the time, you might try Linux Mint 19.3 Tricia. Tricia has the most recent fixes for the LM 19 series.
Wikipedia looks to have a good overview in its “Multiboot” article.
There are also detailed guides around. I think https://itsfoss.com/guide-install-linux-mint-16-dual-boot-windows/ does a good job answering general questions before giving step-by-step instructions.
Welcome to the forum.
The AR Sandbox need fast access to the video card and its 3D acceleration capabilities. Cross-OS containers add layers of data translation that slow hardware access. There may also be user permission problems across OSes.
If you already have a Kinect, it’s worth a try.
Another option is to dual boot into Linux to use the sandbox software.
Use
sudo apt-get install --reinstall libdbus-1-dev, in a terminal window, to restore the missing file. Then try compiling Vrui again.The thing that strikes me most in your photos is that there seems little correlation between the sand and the contour lines. I think I see contour lines drawn crossing over ridges in the sand.
Some thoughts…
Are the Kinect and projector mounted in the same orientation?
Were the Kinect or projector moved after calibration?
After Step 11 (with CalibrateProjector), does the green circle project onto the target disk and follow it as it moves? Do the red crosshairs track near the center of the target disk? See Oliver’s calibration video for an example.
there’s no color on the image.
This may be as simple as accidentally not including the “-uhm” option when starting SARndbox.
