[Chromium-dev] Tracker SPU

[<dr...@bf...>]

Because of its size the following message did not come through the first
time. So here it is again now with links to the patches instead of
attachments.


Some time ago I mentioned that I'm working on the integration of a head
tracking device with Chromium. Here is what I've got so far:

- Patch3: A tracker SPU which listens on a UDP socket for data from a
tracker client. There is a sample of usage in
\mothership\configs\tracker.conf. The sample is for a three wall CAVE
with stereo vision.
Available at http://athena.bfh.ch/projects/cave/patches/Patch3.patch

- Patch4: A tracker client for the Ascension Flock of Birds
(http://www.ascension-tech.com/products/flockofbirds.php) written in C++
with QT for the GUI.
Available at http://athena.bfh.ch/projects/cave/patches/Patch4.patch

- Patch5: A tracker client for the Ascension Flock of Birds written in C#.
Available at http://athena.bfh.ch/projects/cave/patches/Patch5.patch

Both clients need the bird (bird.h and bird.dll) driver available at
ftp://ftp.ascension-tech.com/PRODUCTS/FLOCK_OF_BIRD/Flock_of_Birds.zip.

Some further information is available from our CAVE Wiki at
http://athena.bfh.ch/mediawiki/index.php/Head_Tracking

[Chromium-dev] Tracker SPU

[Gelson R. <gel...@ho...>]

Hi,     I'm trying to use Tracker SPU on Chromium. I have a Flock of Birds tracker with one sensor and my intention is to use all in Windows XP on Cygwin environment. I did built all Chromium  framework (from CVS repository) and it run very well, but when FOBTrackerCSharp app send data to TrackerSPU a warning message tell me that "CR Warning(myServer:0): Tracker SPU: Invalid datagram for tracker SPU" and nothing change in visualization when FOB sensor is moved. I put custom debug message in trackerspu_udp.c and I can see that connection between sockets is working, but i believe that data arrive corrupt. Have somebody idea what is going on? My test environment: 2 pc (host1, host2) running Windows XPhost1: Running CSharp FOB tracker working very well (here I set IP Address  = host2_IP)host2: (Cygwin) Running Python tracker.conf + 6 crserver + 1 crappfacker (here I changed only in tracker.conf listen_ip = host2_IP (almost default configuration) Thanks a lot for help,Gelson  P.S.: Please sorry very much for my bad english!

Michael,

I've checked in your new tracker SPU.  Sorry for the delay.  I've been=20
focused on other projects and your email was way at the bottom of my inbo=
x.

Comments follow...

Checked in.  Though, the patch didn't apply cleanly to CVS head so you=20
should get the latest code from CVS and check that it's OK.

Also, could you please add some documentation?  In particular, the=20
cr/doc/configoptions.html file should list all the config files for the S=
PU.

It looks like patches 4 and 5 add demo programs in the spu/tracker/=20
directory.  That's probably not the best place.  All the deme programs=20
go under the progs/ directory.  Could you redo your patches?

Perhaps you could add that info to the Cr docs.

Brian,

The attached patch adds documentation for the tracker SPU. It refers to=20
the version of the SPU which I sent to you as patch6 and patch7 last=20
Friday. I tried to incorporate all your suggestions from your last mail.
