Hi Ziv,<div>You are right. The tracker would be directly connect to the system in my application, so I don't need to broadcast the frames.</div><div>Moreover Polaris spectra that I am using uses serial interface, so OpenIGTLink is probably an unnecessary layer.</div>

Hi Somi,<br>
<br>
OpenIGTLink is probably not what you are looking for. Here's how it
works:<br>
OpenIGTLink is a message passing protocol
(<a href="http://www.na-mic.org/Wiki/index.php/OpenIGTLink" target="_blank">http://www.na-mic.org/Wiki/index.php/OpenIGTLink</a>) that among others
supports passing of transforms. <br>
Slicer3D (<a href="http://www.slicer.org" target="_blank">www.slicer.org</a>) uses this protocol for tracking in image
guided interventions. The way they do it is through
IGSTK+OpenIGTLink over TCP/IP sockets. IGSTK provides a standalone
program that does the tracking and transmits the OpenIGTLink
messages through sockets to the Slicer application. You can run the
two programs on the same computer or on two separate computers
connected via ethernet.<br>
<br>
I am pretty sure this isn't what you wanted.<br>
<br>
With regard to the multi-threading library that I mentioned, this is
original ITK code with minor modifications, mainly removal of code.
Given that this is a modification for my uses:<br>
a. The license is the same as for ITK (free for any use, no strings
attached). <br>
b. There is no support for this specific library as I created it for
my uses. Given that it is 99% original ITK you can ask questions on
the ITK list for any issues.<br>
c. It is minimally tested as I am relying on the original ITK
testing. Hopefully my modifications are minor enough that I have not
introduced bugs into the code. You can always compare its behavior
to that of the official ITK release, just change the library to
which you link, your code remains the same as the interface did not
change. If the behavior is the same then my modifications did not
introduce bugs that aren't already in the original code ;).<br>
<br>
hope this clarified things<br><font color="#888888">

<div>Ziv,</div>
<div>We have an application with custom features,display and
tracking code (currently supports Polaris only) . We want to
separate the tracking code from this application,</div>
<div>so that user may be able develop and use their own trackers
and are not restricted to Polaris. We can implement custom
tracking classes for various trackers,</div>
<div> but tracking is not our core competence and we would like a
toolkit which is widely used, robustly tested, supports major
trackers and well documented, so that its easy for users to
debug.</div>
<div><br>
</div>
<div>So I decided on using IGSTK. However if I use IGSTK I would
have to provide ITK/VTK/IGSTK libraries with my application,
even though I am using only</div>
<div>few ITK/VTK objects ( <span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse">igstk::Transform for itk , any VTK
object ? ) I could implement my own Transform structure as you
suggested. However to use your MT-library, there may be some
issues:</span></div>

<div><span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse">b)
How much support is available for it ??</span></div>
<div><span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse">c)
Has it been rigorously tested or still in development ??</span></div>
<div><span style="font-family:arial,sans-serif;font-size:13px;border-collapse:collapse"><br>
</span></div>
<div><br>

<div>
I also came across OpenIGTlink @ <a href="http://www.na-mic.org/Wiki/index.php/OpenIGTLink" target="_blank">http://www.na-mic.org/Wiki/index.php/OpenIGTLink</a></div>
<div>I am not very clear about relation between IGSTK and
OpenIGTLink ? does IGSTK use OpenIGTLink protocol ?</div>
<div>or OpenIGTLink and IGSTK are completely different ?</div>

<br>
IGSTK is build on top of ITK/VTK. It is not possible to
isolate the tracking component as the way you described.<br>
<br>
To decouple your own application with IGSTK, you can try use
the OpenIGTLink library.<br>
<a href="http://public.kitware.com/IGSTKWIKI/index.php/Using_OpenIGTLink_in_IGSTK" target="_blank">http://public.kitware.com/IGSTKWIKI/index.php/Using_OpenIGTLink_in_IGSTK</a><br>
<br>
You can start with the example application in IGSTK:<br>

Hi,<br>
Do the Tracking component of IGSTK depend on ITK/VTK ?<br>
<br>
If not is it possible to build IGSTK only for tracking
with no dependencies<br>
on ITK/VTK toolkits ?<br>
<br>
I am trying to integrate the tracking component of IGSTK
in my application,<br>
I have my own Display/ Image processing etc code.<br>
<br>
Thanks,<br>
Somi<br>
