[IGSTK-Users] Threaded IGSTK views with Qt

[Cheng, Patrick]

Hi Alo,

 

You could consider doing it the other way around: spin off your resource
intensive computation into a separate thread.

 

Take a look at igstkTracker class where we use ITK thread to create a
separate thread to interact with the physical tracker.

 

itk::MultiThreader::Pointer     m_Threader;

m_Threader = itk::MultiThreader::New();

 

m_ThreadID = m_Threader->SpawnThread( TrackingThreadFunction, this );

 

ITK_THREAD_RETURN_TYPE Tracker::TrackingThreadFunction(void*
pInfoStruct)

  { 

  ....

  }

 

Hope this helps,

 

Patrick

Subject: [IGSTK-Users] Threaded IGSTK views with Qt

 

We're using IGSTK with Qt and would like to move the view rendering to a
separate thread to avoid GUI slowdowns while rendering resource
intensive (low-FPS) scenes. Is there a way to move the views/rendering
out of the main Qt thread?
