[IGSTK-Users] Multi-Thread in IGSTK

[Özgür Güler]

Hi Nova,

grabbing video from a video device is already in a separate thread.
The "InternalThreadedUpdate" function runs continuously in a thread
and grabs video image from a video device or pose information from a
tracker.

You can use the platform independent thread framework from ITK to
build your own thread: itkMultiThreader   (see igstkTracker class as
an example)

Actually you set up and start the Pulse Generator and the IGSTK
infrastructure does the rest. The Pulse Generators triggers an update
for each rendered object on the display. This assures that all objects
seen on the display are up to date.
Please read following chapter in the IGSTK book.
Chapter 5.5 Timing

best,
Ozgur
