Re: Significant slow down and lag with moving trackables & V

I've done a little more work trying to figure this out. My problem seems to be related to the VRPN streaming engine, somehow. I'm also going to post this problem to the VRPN listserv, but can anyone help me with this? Currently, I have up to 6 moving trackables (robots), and each of them subscribes ...

Significant slow down and lag with moving trackables & VRPN

I'm trying to track up to ten different trackables simultaneously. These trackables are independent robots within my ~4m x 4m x 3m lab space, and each trackable is made up of 3 markers. I have 22 V100:R2 cameras on 4 OptiHubs, and I'm currently running TrackingTools 2.4.0-beta1 64-bit. It's running ...

Re: USB devices failed (or disconnected?)

<t>Another note -- in Windows Task manager, the memory usage of TT is also much more steady after fixing this setting. I had previously observed the memory usage going from ~230MB at startup to much higher, up to 700MB over one day, whereas now (not a full day, but over an hour) it seems to be rock ...

Re: USB devices failed (or disconnected?)

<t>I believe this is now resolved.<br/> <br/> After a suggestion by NaturalPoint's Dustin that my USB ports might be malfunctioning I did some Google searching, and turned up some results where intermittent behavior may be related to Windows power management, I inspected that option for each of the ...

I left TT running over night; the Windows error is "USB Device Not Recognized".

USB devices failed (or disconnected?)

<t>From time to time, the computer running TrackingTools makes the sound indicating that a USB device has disconnected ("BA dup"), sometimes more than once, and then shortly after that the reconnection sound ("ba DUP"). A few seconds later, some number of cameras in the 3D perspective view move to t...

Re: VRPN Stream python, multiple Rigid Body objects

<t>For those who may be interested:<br/> the latest version of VRPN (available through their git repository as of a month or two ago) now has a new version of python wrappers that are handwritten.<br/> <br/> I can now get info for all of my Rigid Bodies -- currently I have 13 in my space.<br/> <br/>...

VRPN Stream python, multiple Rigid Body objects

<r>I have found some sample python code on the web which works relatively well if I'm only tracking one Rigid Body. However, if I want to track more than one (13, actually) I can get the change handler to report all 13 positions -- but there is no identifying information for one body is which.<br/> ...
