[IGSTK-Users] Get position tools

[Eric L. B.]

Hi again!!!
 
I wrote about how to get the position of a tool with a Polaris Tracker.
I has received a response, with some code which define an observer, but i have a little problem with this part:
 
         typedef itk::ReceptorMemberCommand < Self > LoadedObserverType;
 
What typedef is Self??????????
There is an error: Undeclared identifier
 
The whole code received is:
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
//  define an observer in your main class
#include "igstkEvents.h"
typedef itk::ReceptorMemberCommand < Self > LoadedObserverType;LoadedObserverType::Pointer m_TrackerToolUpdateObserver;// set a callback function to itm_TrackerToolUpdateObserver = LoadedObserverType::New();m_TrackerToolUpdateObserver->SetCallbackFunction( this, &MyClass::TrackingCallback );// the callback function
void MyClass::TrackingCallback(const itk::EventObject & event ){  if ( igstk::TrackerToolTransformUpdateEvent().CheckEvent( &event ) ) {     typedef igstk::TransformObserver ObserverType;     ObserverType::Pointer transformObserver = ObserverType::New();     transformObserver->ObserveTransformEventsFrom( m_TrackerTool );     transformObserver->Clear();     m_TrackerTool->RequestComputeTransformTo( m_WorldReference ); // some reference e.g.  igstk::AxesObject::Pointer m_WorldReference;     if ( transformObserver->GotTransform() )     {          igstk::Transform::VectorType translation;         // get the translational component          translation = transformObserver->GetTransform().GetTranslation();         // get the rotational component (quaternion)          igstk::Transform::VersorType rotation;          rotation= transformObserver->GetTransform().GetRotation();      } }}// and don't forget to add the observer to the tracker toolm_TrackerTool->AddObserver( igstk::TrackerToolTransformUpdateEvent(), m_TrackerToolUpdateObserver);///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
 
 
 
I hope someone can help me please, or give me onother option to get coordinates of tools, please... :(
Thanks, i will be waiting for some response :D
