    Oliver,

    thank you for responding to my other posts. With this new update, will it work for a system with the following specs?

    -Computer-
    Processor : 2x AMD Athlon(tm) 64 X2 Dual Core Processor 4200+
    Memory : 2047MB (653MB used)
    Operating System: Ubuntu 15.10
    User Name : sand (Sand)
    Date/Time : Sun 08 Nov 2015 05:20:01 PM EST
    -Display-
    Resolution : 1024×768 pixels
    OpenGL Renderer : Unknown
    X11 Vendor : The X.Org Foundation
    -Multimedia-
    Audio Adapter : HDA-Intel – HDA NVidia

    Operating System
    —————-
    -Version-
    Kernel : Linux 4.2.0-16-generic (x86_64)
    Compiled : #19-Ubuntu SMP Thu Oct 8 15:35:06 UTC 2015
    C Library : Unknown
    Default C Compiler : GNU C Compiler version 5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2)
    Distribution : Ubuntu 15.10

    My GPU is an AMD Radeon 1540/1520. When I run the main Sandbox application, the 3D rendering is painstakingly slow to react to the mouse and keyboard. I have attempted to complete the Kinect and projector calibration steps but was not very good at it as I received:

    Calibration error: Some tie points have negative projection weights. Please start from scratchCalibration error: Some tie points have negative projection weights. Please start from scratch.

    I will be reattempting tomorrow but did not know if it would be a futile attempt if my machine is not up to par?

    RickM,

    no, I did not have any luck with the RaspberryPiII. I thought the same as you about the graphics being to demanding for the RP2, but I was a little wishful when I saw another post on this forum form a user who stated that they were successful putting this program on one. I responded to the user’s post on this forum, but they never responded back so I moved on to another system.

    The problem I am facing now is a new error. When I run the main Sandbox application I receive this error:

    Cannot fix projector view due to exception IO::StandardFile: Unable to open file /home/sand/src/SARndbox-1.5-001/etc/SARndbox-1.5/ProjectorMatrix.dat for reading due to error 2
    0.155481 x 0.15066

    Problem is, I cannot find the file ‘ProjectorMatrix.dat’ in any directory I have on the machine.

    I am using a system my school provided to me as setting the AR Sandbox up is a project I have for this semester. Below are the specs for the machine given to me:

    I am attempting to complete these steps on a Raspberry Pi 2 with QUAD Core Broadcom BCM2836 CPU and 1GB RAM. The device came with an 8GB micro SD card. I am also using the latese Kinect device that came out in Winter of 2014. I found a forum on here where someone stated they were able to run these steps successfully on a Raspberry Pi and I commented on that forum as well. Just thought I would post here to see if there are any suggestions for the error I am getting.

    I started with Step 4 as I am running on Raspbarian (as mentioned in my previous post) and am NOT using a dedicated graphics card. I saw no reason to complete Step 3.

    After issuing the commands in the first part of Step 4, I receive a GL error. I know that this error is mentioned above:

    If you receive “GL Error: …” while running any of the Kinect or Sandbox applications, check that you have the proper vendor-supplied drivers for your graphics card installed. The AR Sandbox application will run poorly in software-emulated OpenGL mode.

    I am not using any dedicated graphics card, just the Raspberry Pi, so I am not sure what to do when receiving this error. Here is the specific error:

    Caught exception GLContext: Unable to open display default while initializing rendering window 0
    Caught exception Vrui::startDisplay: Could not create all rendering windows while initializing renddering windows

    This error was thrown after the response:
    Running ShowEarthModel application. Press Esc or close window to exit.

    No window popped up with a spinning globe as mentioned in the Complete Installation Instructions. I assume the error was thrown because the a window tried to render and was unable to do so. I am at a loss as what to do next?

    Thank you,

    Hello, I am also a student at a university who has been given the task of running the AR Sandbox on a Raspberry Pi. I assume you also do not have a dedicated graphocs card and are purely running the software off a Raspberry Pi alone? I have not been as successful as you seem to have been, as I am receiving several errors with installation. I have followed the “Complete Installation Instructions” provided on this site, and still have issues.

    I read on here, under Common Issues (READ FIRST) http://lakeviz.org/forums/topic/common-issues-read-this-first/, that the calibrtion steps should be skipped unless unsatisfactory behavior results. Therefore, I completed steps 1-4 then skipped to step 11.

    I must note that after running the script in step 4, I did not have this happen:
    “The script run in the last command will ask you for your user’s password to install prerequisite libraries, and then build the Vrui VR toolkit. That will take a little while and produce lots of output, and at the end you’ll be greeted by a spinning globe in a window. Close that window and go back to the same terminal as before:”

    No window opened with a spinning globe. I still proceeded to step 11.

    When I tried to run the main application, I get the error:
    0.155481 x 0.15066
    Caught exception GLContext: Unable to open display default while initializing rendering window o
    Caught exception Vrui::startDisplay: Could not create all rendering windows while initializing rendering windows

    I am using a Raspberry Pi 2 Model B with a Quad Core Broadcom BCM2836 CPU and 1GB RAM.

    I read what to do with the GLContext error but the instructions on that did not help as I am not using a dedicated graphics card of any sort. Any suggestions?
