Bonus round: I think I read something about changing the drain/evaporation rate somewhere on the forum, but can’t find it now. Is there a setting for this, or would it require another script addition? The installation is primarily for school-age children, so a faster or even instant drain rate would help with keeping their attention.December 16, 2022 at 9:05 am in reply to: Adding assigned water keys when other modifications are already present #2414
Looking at Step 15 in the instructions, it looks like I would add only the following to SARndbox.cfg:
section Tools section DefaultTools # Bind a global rain/dry tool to the "1" and "2" keys: section WaterTool toolClass GlobalWaterTool bindings ((Mouse, 1, 2))
And then with the endsections adjusted the file would look like this?
section SARndbox section Camera # Configuration parameters for Kinect v1 compressDepthFrames true smoothDepthFrames false endsection section Tools section DefaultTools # Bind a global rain/dry tool to the "1" and "2" keys: section WaterTool toolClass GlobalWaterTool bindings ((Mouse, 1, 2)) endsection endsection endsection endsection
According to Step 17 in the instructions, once I add the correct reference to the startup icon script, the autorun will reference it and I should be all set.December 16, 2022 at 9:03 am in reply to: Adding assigned water keys when other modifications are already present #2412
Below is the code in the shell script in the desktop icon (i.e. what you get when you right-click the icon and open with text editor). Could someone explain what the syntax is telling the computer to do here, and what I need to add to make it reference SARndbox.cfg?
#!/usr/bin/env bash if [[ $1 -ne 0 ]]; then sleep $1 fi ~/src/SARndbox-2.3/bin/SARndbox -mergeConfig ~/src/Vrui.cfg -uhm -fpv
I did a file search on our system and SARndbox.cfg exists and contains the following:
# Configuration file for SARndbox application # Copyright (c) 2016 Oliver Kreylos section SARndbox section Camera # Configuration parameters for Kinect v1 compressDepthFrames true smoothDepthFrames false endsection endsection
Hi Dr. Kreylos. Sorry to bother you again but I have another post stuck in moderation from including hyperlinks and/or code. Could you take a look please? Thanks.December 7, 2022 at 8:36 am in reply to: Sandbox software and Mint OS version compatibility #2392
Do you plan to use the sandbox computer for anything other than the sandbox? If not, does it matter that there will not be OS updates? Unless and until there is a new sandbox release, LM 19 will continue to work.
No, this computer is only for the sandbox. It probably doesn’t matter, but better to ask than assume when I don’t have the experience myself.
I’ve hit a snag updating the BIOS and will probably move on to installing Mint 19. With the problems I’ve been having I don’t want to introduce complexity by needing to modify Mint 21.
Thank you for the additional info–I’ve added it to the documentation and that’s reassuring, Sean–our age range is elementary students so there’ll probably be multiple students at once as well.
Now if I can just get the driver installed…
Awesome, thank you!
It turns out the organization we got our sandbox from never used the water functionality and a quick check in the tower case explains why–whoever set up their system didn’t use a computer with a discrete GPU. So we need a graphics card. The computer guy we consult with recommended a card with these specs:
4GB, 128-bit, GDDR6
Boost Clock: 1620 MHz
Coprocessor: NVIDIA GeForce GTX 1650
Will this card work?
I am having problems getting posts and comments to go through. I will keep trying to get my actual question posted in a comment here.November 22, 2022 at 11:34 am in reply to: Further calibration problems–green indicator problems and no red crosshairs #2345
Test comment. Will this post?November 21, 2022 at 1:24 pm in reply to: Further calibration problems–green indicator problems and no red crosshairs #2344
Thank you for the tip, the old forum was very useful, although it looks like not all of it wound up archived. I had been taking each set of tie points at the same height. I will try varying within the set and hopefully that plus having our sand will do it.

The sand just arrived today, actually. Checking the archived forum now.November 9, 2022 at 2:28 pm in reply to: Further calibration problems–green indicator problems and no red crosshairs #2317
This was the problem. I replaced the pipe strapping with a thin allthread rod and was able to get a green target. I took tie points at four height levels and two base plane levels (two heights for each) and got what seems like good calibration according to the red crosshairs following and lining up with the target throughout the sandbox. When running the sandbox program contour lines matched up with the objects I placed in the box.
However, when I exited the calibration, the command window had the message:
“Calibration error: Some tie points have negative projection weights. Please start from scratch”
This message was also on all previous calibration attempts, but I had hoped fixing the target problems would resolve it. What does negative projection weights mean and how do I fix it?
Hello. Sorry for replying to this but there doesn’t seem to be a way to contact you as a moderator. I have a post that into the mod queue, probably because it contains hyperlinks.
That makes sense now. In a way this is easier b/c the previous installation was working at the time they mothballed it, which means I’m just following steps. On the other hand, I’d be getting a better understanding doing it from scratch.
