    Hi, wondering if anyone would like to share their os/software/hardware success stories with the AR sandbox?

    I have been failing at getting the software to run property using Ubuntu 12.04 with the Nvidia GTX 760 (Kinect-2.7, SARndbox-1.5, Vrui-3.0-002). There is a visible blue line about an inch inside the border of the physical sandbox that we can’t get to go away. We have tried all sorts of Nvidia driver combinations. In addition RawKinectViewer and KinectViewer freeze while any key is held down so it makes calibration a beast. When we upgraded to Ubuntu 14.04 the water animation stopped working all together. When we attempted to use the Nvidia GTX 770 card with either version of Ubuntu SARndbox froze after about 5 seconds of running. Curiously the water would start to animate again while moving the mouse around but the terrain wouldn’t update.

    Our own sandbox is running Nvidia driver version 343.36 on a GeForce GTX 680, and we have the blue rectangle problem.

    Can you describe that problem in more detail? I don’t think I’ve heard of this one before.

    Could this work on a Bootcamp Mac (2.5GHz i5 with 8GB and Intel HD Graphics 4000 1024MB) running Linux? Would you recommend me trying this?

    1. Is the visible blue line something like this?

    If so, it might be a matter of calibration. We’ve been able to hide it by panning and zooming in KinectViewer and saving that specific view. Seems to be related to zero elevation and virtual sandbox bounds. Some calibrations that have come out better than others do not show the line at all, and we can use the -fpv parameter in running the app. On some others, we’ve manually tweaked the image and have resorted to loading a pre-saved View.

    RawKinectViewer and KinectViewer freeze while any key is held down

    I’ve experienced that myself, it seems to occur when the launched app isn’t focused/active window. After launching for example RawKinectViewer, clicking on it with mouse before pressing anything on keyboard seemed to solve it for me.

    the water animation stopped working all together.

    This is most probably related to drivers and graphics card. In one calibration, just restarting the computer solved the problem for me. Once it came and went without any apparent changes to the system. I had same erratic symptoms with rain making. A restart fixed that – probably had something to do with rendering as well.

    Curiously the water would start to animate again while moving the mouse

    Locked/frozen screen until mouse is moved is something I’ve seen myself and this was fixed with installing proper graphics drivers and instructing the dedicated video card to run the app. Our last installation was on lenovo Y50-70 with GTX 860M, Fedora 19. It was a pain to get switchable graphics working on Fedora to being with. After updating to Fedora 21, disabling SELinux, reinstalling SARndox related software, installing proprietary drivers, Bumblebee etc, I finally managed to get it working. Without assigning dedicated video card to run the sandbox app, though, the video feed would freeze unless the mouse was moved.
