    Daniel,

    Could you please post the hardware in your setup?

    Javier,

    I didn’t try this but I thought that the only part of the program that needs a good graphic card is the water simulation. If you are OK with that, you can certainly give it a try. You said the calibration didn’t go well. What happened? I had some issues with calibration and I think it was the Kinect was a bit too far away from the sand box.

    I am wondering about the same thing. I suspect that the answer is not trivial.

    Marian,

    What are the reasons that compelled you to not install online? As far as I know, the source files of the ARSandbox are all online. If you want to install offline, you must obtain the files using another computer that is online.

    I have experienced this also. My setup is a Dell Inspiron 3668 with i3-7100 4GB and GTX 750 TI 2GB. I didn’t do an actual startup script but instead used the GUI feature of startup programs. It is a terrible GUI feature. There is no order which program runs first and next. I wrote a simple script to run that does a 30-second delay before running ARSandbox and added it to the GUI startup programs and it works. I don’t really like the solution. I’m more used to Debian where I run startup script after say auto login. I will look for ways to run ARSandbox after everything loads.

    David,

    I am with you. I produce and maintain open-source projects as well, software and hardware. Once in a while I get $5 to $20 donations from people I don’t know! It’s not really what I have to get but that’s what’s reminding me that people value my contribution. A post on my blog saying that my stuff is useful would be nice too. A small monetary donation per unit sold, helping noobs getting started with their own build, spreading the word, contributing to the source code… Anything helps I suppose. That’s why I’m here. I built two prototypes and my son loves playing with the sandbox! I’m also writing a proposal to make more units for water resources education in my state.

    Lingthay,

    It’s a wonderful tool! I can’t speak for Dr. Kreylos but I thought that more units means more science education and more people care about science and environment. I’d say it’s good for you!

    David G.,

    I’d love to see how you placed the mirror in the path of the projected image. Let us now when you have docs published.

    So are you saying that the flickering is probably due to the Kinect plugged in to a USB 2.0 port on your old computer? I read somewhere (maybe not the most updated info) that Kinect’s driver only works on USB 2.0 port or something. Can you confirm that you connected your Kinect to your new computer’s USB 3.0 port with “SS” symbol next to the port and blue plastic inside the socket? I’ve been looking for gaming laptops that still feature at least one UBS 2.0 port. Maybe I shouldn’t have.

    I found reference here. Dr. Kreylos recommends the Kinect 40″ above the bottom of the sandbox.

    Read the description below the figure.

    Hi,

    I think you are in the wrong folder. Here is the folder structure:

    Notice that both CalibrateProjector and SARndbox are in ~/src/Kinect-3.2/SARndbox-2.3/bin

    You should do cd ~/src/Kinect-3.2/SARndbox-2.3/bin and then run the two commands. Hope it helps.

    David,

    My system is about the same situation as yours, with a regular projector. It’s pretty tall! One thing I learned is that the Kinect should be mounted closer than the regular projector, around 1.2m (45″) from the bottom of the box. With Kinect mounted so far away as our regular projector, we were unable to calibrate the projector with targets.

    Thanks. I’m using GTX 750 Ti now. At times the system (i3-7100 dual core 3.9GHz max) still reports running out of time. It’s working fine despite of the messages. For my next system, I’ll give i7 a try with a better video card.

    Francisco,

    What do you mean by “flickers”? I’ve had some issues with calibration but I thought maybe that’s because my Kinect was too far away. I got it closer and the calibration worked.

    elisek,

    Thanks for the pointer. I took a look at the .cpp, but felt a bit lost. Too much dependence on libraries. I’ll have to hack and see how it goes. Maybe spend sometime with the VRui project hopefully it has good documentation. I thought that adding these features will make the sandbox more interactive in a computer-techie free space, where users just turn big knobs instead of using mice and keyboards.

    Looks awesome! Is this “kinetic” sand? You have deep gorges and tall hills. Textures are well attached to the model. So I guess your capture device doesn’t rely on IR grids?
