[IGSTK-Users] Reg Tracking component

[Patrick Cheng]

Hi Somi,

If you want to have a tracker independent implementation, then 
OpenIGTLink is your best bet.

OpenIGTLink is a socket communication protocol for packaging transforms, 
images, and other IGT related data. It currently has implemented TCP/IP 
protocol for the data transfer.

There is an example in IGSTK for using OpenIGTLink to broadcast tracking 
data. You will need to write some OpenIGTLink in your application to 
receive and unpack that data package. Examples can be find in Slicer:
http://www.na-mic.org/Wiki/index.php/OpenIGTLink/Slicer

Both IGSTK and OpenIGTLink have BSD style license, which means it can be 
used free of charge in commercial products. IGSTK tracker component is 
pretty stable and has been tested by the user community for a few years.
