Dear All,

Here I get the NDI trakSTAR device, after using the OpenIGTLinkIF module, it seemed that the device can be connected.

Next, I want to get the position, and show the point stream in the Slicer view.  
But I can not find a step by step method.  
Seek for help on line…  
thanks

I can not get the stylusTipToReference, maybe that was the data source.  
so, any more suggestions?  
thanks again.
