    Digging up an old thread here, but experiencing the same problem…

    The initial sandbox view that is 90* to the side is also present during calibration, leading to a non-green disc during tie-point acquisition.

    Has anyone had similar problems and found a solution?

    Were any major changes necessary to fix the crash issue?

    Would there be any reason why this DEM tool might not work well with other planetary coordinate system raster’s (Mars for example)?
    Having difficulties getting anything other than a red map motivates this question.

    @ ajy00
    Your solution to cycle through fluid options with a single button is a great hardware solution!
    Thanks for sharing this.

    Hello fdourado,

    For post processing with GIS,
    DEMs can be saved by binding a “Save Bathymetry” tool. When the associated key/button is pressed, the current surface will be written in USGS DEM format. -Oliver, Posting 102452
    Creation of this tool works like any other custom tool, or can be prewritten into the SARndbox confit file. It is defaulted to save the produced DEM in the SARndbox file directory (~.user/src/SARndbox-2.3/).

    Not to sure about displaying slope in an active SARndbox session, although that would be a cool feature.
    Maybe even a dynamic hot/cold color map of slope steepness?

    in reply to: Slope and topography #103287


    There is a really great tool built into the most recent SARndbox software. It enables a digital elevation model (DEM) of the sands surface to be exported, which can then be opened in most geographic information system (GIS) software.
    The most user friendly open source GIS I have found is named Quantum GIS, which is fairly easy to use while also including some advanced capabilities.
    For example, if you export a DEM from the sandbox and open it into Q-GIS, you can easily do topographic slope profiles with the (also free) plugin called Profile Tool.
    Hope this might answer some of your needs…

    in reply to: SARndbox Freeze? #103217


    Problem was software based. Exact issue unknown.
    Reformat HD, reinstall of Linux Mint 18.1, and reinstall of all SARndbox utilities has stopped Ui freeze problems.

    Side note;
    Although it doesn’t appear to affect the SARndbox, the terminal fills with this while running…

    Any insight on the cause and if its an immediate concern?

    in reply to: SARndbox Freeze? #103179


    During the freeze problem, the Kinect indicates constant power (constantly blinking green led).
    This would appear to suggest that this is a software issue.

    Will yield on further posting to hear if others might be able to share insights.

    in reply to: SARndbox Freeze? #103170


    Further hardware testing reveals that the Kinect device appears to get reasonably warm during use, especially during the OG freeze error.
    Since the nature of the problem (repetitive software disconnect while all hardware remains connected), inclines me to figure this might be the source of trouble.

    As I understand it, there is a cooling fan inside the unit which should be activated by a thermistor when temps rise.
    At the supposed location of the fans there doesn’t appear to be indication audible running or air movement when the unit warms up simultaneous during expression of the OG freeze error.

    Can anyone chime in on their Kinects temperature characteristics during use, especially when lots of ‘fluid’ is active in the box?
    Also, does such a diagnosis sound plausible and possibly warrant purchase of a new Kinect sensor?


    in reply to: SARndbox Freeze? #103146


    Because the SARndbox program would not start when using the -ws 0 0 command via;

    SARndbox -wts 640 480 -uhm -fpv -ws 0 0 -cp ~/.../Control.fifo

    Is it possible the local fluid calculations are the source of the problem?

    Also, further testing with -wts 320 240 did not seem to help either.
    Detail on this low resolution test;
    When adding sufficient water, the dynamics are calculated for a few seconds without trouble then rapidly increasing frame rate lag freezes the software in 5 – 10 seconds. Closing out requires using the keyboard Alt+Tab combo to exit the SARndbox program via terminal manually rather than Esc in (frozen) full screen context.

    Funny how a few days so easily turns into a few weeks.
    Please pardon the delay.

    @Oliver Kreylos
    Tested the two recommended actions, both of which included periodic arm waving within the sensors view space;
    > KinectViewer -compress -c 0 expressed no freeze or lag for extended runtime (~20 min.)
    > SARndbox… + -ws 0 0 cause the SARndbox to not startup with the following full command string;
    SARndbox -wts 640 480 -uhm -fpv -ws 0 0 -cp ~/.../Control.fifo
    I recently found this posting of similar context in another forum. Of interest is the following claim,

    …or hardware getting bored and switching to standby

    Could this be a possible cause for the lag and freeze? If so, are there any ways to test and mitigate?

    All the physical connections associated with the Kinect appear to be nominal. I suppose the next step is purchasing a new Kinect sensor, USB cables, and USB controller – but impoverished pockets would prefer such as a last resort…

    in reply to: SARndbox Freeze? #103124


    I will pursue these recommended actions and reply with an update withing the next few days.
    Thanks for rapid answers.

    Side (possible related) question;
    Will the Kinect have problems with USB 3.0 vs USB 2.0 ports?

    in reply to: SARndbox Freeze? #103116


    To assist troubleshooting, here are the specs for the workstation in question;

    	ID-2: USB /dev/sdb 

    These appear to meet the suggested components from the ‘sticky’ user guide.

    To elaborate on the problem further;
    The freezing occurs during extensive fluvial simulations, eg when lots of hands are adding water or there is already a large volume of water being simulated.
    I have reset the SARndbox resolution to 640×480 via command line which did not improve the issue.

    Does anyone have any other advice or similar experience with such a consistent freeze error?

    in reply to: AGU sand #103114


    Hello Greg,
    This is a bit off topic but I had a question regarding the posted images of your mobile sandbox at the 2016 AGU conference…
    Posting Link
    Via forum posting appears to be the only way to contact you directly, as I was unable to find a private message option.

    I built an oak basin for our uni. geo. department mobile SARndbox 1.5 years ago. Upon recent checkup, I discovered the oak boards have split severely, compromising the workstations function.
    The plan is to rebuild the setup – and the highers up like the idea of emphasizing mobility for outreach off campus.
    Would you consider a dialog about your design as shown in the link above?
    I could start a new forum post titled appropriately so that others might benefit as well (Packable SARndbox Design).

    Consideration appreciated.

    I submitted a similar question a few months ago which might be helpful;
