[IGSTK-Users] Transform Data Export

[Ziv Yaniv]

Hi Jake,

You should take a look at the OpenIGTLinkTrackerBroadcasting example. 
You can easily modify it to do what you want (writing to file instead of 
to socket). It already works for multiple tools, with or without a 
reference frame. Please read the IGSTK book for the full details.

All you need to do is modify the ToolUpdatedObserver class found in 
OpenIGTLinkTrackingBroadcaster.h. Instead of the m_Sockets and 
m_PositionMessage members you will have an ostream member which you 
write the data to, this will happen in the Execute method which you need 
to slightly modify.

             regards
                 Ziv
