Hello,
My 10th grade students and I just finished building our augmented reality sound table. Thank you so much for making this project.
The calibration all went well. We got around some permissions issues and file placement issues during the setup.
Unfortunately, we can’t seem to get the rain/water functionality to work even though our topographical map is projecting perfectly. Any help would be greatly appreciated.
Thank you!Does water work when you add it globally? Press and hold some key, e.g., “1”, and move the mouse to highlight “Manage Water” in the tool selection menu that pops up. Then release the key you pressed. Then press and release a second key, e.g., “2”.
This will bind a water tool to the two keys you chose. Now press and hold the first key to add water everywhere.
Water was not appearing when we pressed the keyboard keys, either with the presets in the config (1 & 2) or when assigning new keys.
We are using Linux Mint on a Mac Mini, but I would expect the water to be slow rather than not appearing at all.
Thank you.
I am realizing that this might be related to an installation problem. When I ran the installers everything installed to the home folder and I had to copy files to the system folder manually. There might be something I missed. Should I run the installers again with a different command or look for a particular file and verify it is in the correct location?
Thank you.
Moving files after installation can cause them to not be found by other parts of the software. Why did you need “to copy files to the system folder”?
I recommend removing and recompiling Vrui, Kinect, and SARndox.
I tried rebuilding the SARndTable application but still no water. I then thought that the problem could be the version of Linux Mint (I was on 20.3). So I installed 19.1 which is linked to in the instructions. I went through all the instructions again and no water. I am suspecting the issue could be the Mac Mini, but I was hoping I might be missing something else. I am going to try with a new computer.
In case anyone knows what these errors mean, this is what I was getting (in Terminal) after the setup, but the program did run without water appearing:
user@linux-pc:~/src/SARndbox-2.8$ ./bin/SARndbox -uhm -fpv
Terminated Sandbox due to exception: USB::Device::open: Insufficient device permissions
user@linux-pc:~/src/SARndbox-2.8$ sudo ./bin/SARndbox -uhm -fpv

Vrui: Unable to inhibit screen saver due to exception Vrui::ScreenSaverInhibitorDBus: No screen saver found on session DBus

…Thank you for posting this output.
The “glPrintError: Invalid framebuffer operation” message is a bit generic, but likely means the display card or driver will not work with SARndbox. Do those lines appear only when you try the rain gesture?
I think your plan to use a new computer is the easiest path forward.
That makes sense. I guess that answers whether the software works on a Mac Mini (and the answer is not out of the box).
I got approval to purchase a desktop. Hoping to get it set up before the end of the week.It is hard to tell if the error is only being printed when I try to add water since I was not looking at both windows simultaneously.
Thank you!
Yes, the AR Sandbox’s water simulation does typically not work unless there is a discrete GPU to run the necessary calculations.
The other errors you were seeing (permission problems when accessing Kinect and needing to run SARndbox with sudo, calibration file not existing, etc.) are due to something going awry during software installation. Please follow the steps in the software installation instructions carefully.
Thank you for all your help. I got the program working on the HP i3 Gaming unit you posted on the current hardware topic.
The setup was almost seamless. And it is all working perfectly. Now I just need to pick my preferred settings for water evaporation speed, since I don’t have a “dry” button set up.
