[IGSTK-Users] reg Polaris Spectra tracker

[somi]

Hi,

I have a Polaris tracker with 4 tracking tools attached to it.
During the tracking update look I use "
tracker_tool->RequestGetTransformToParent() "
to get the transform.  See the pseudo-code below for details.

How do I make sure that the transform received for all the Tracker tool
objects is from the same
frame. Polaris frames have a unique frame number for each tracking data,
which I could probably use. Is there any way to access it ?


UpdateLoop()
{

     // Update Tool 1
       tracker_tool1->RequestGetTransformToParent();
        if (coordObserver1->GotTransform())
       {
            TransformType transform;
            transform = coordObserver1->GetTransform();
            if ((is_visible = transform.IsValidNow()))
                   {
                   copy transform data
                    }
         }




          // Update Tool 2
       tracker_tool2->RequestGetTransformToParent();
        if (coordObserver2->GotTransform())
       {
            TransformType transform;
            transform = coordObserver2->GetTransform();
            if ((is_visible = transform.IsValidNow()))
                   {
                   copy transform data
                    }
         }



 .... update other tools
 }


here, coordObserver is an igstk::TransformObserver



Thanks,
Somi
