Technology/Function description

• Exposing the Tracker functionality of IGSTK to Slicer
• How to integrate event loops between trackers and GUI Tcl main event loop.
  • Suggestion:
    • Use sockets in order to send data from the tracker and read it during the blocking stage of the DoOneStep() action in the main Tcl event loop.

Potential application in IGT

• Provide Tracker functionality in Slicer
  • Aurora Tracker
  • Polaris Tracker
  • Micron Tracker
  • Potentially add Robots as trackers (Johns Hopkins)

Which part is already in Slicer

• IGSTK compilation configuration
• MRML scene graph structure
  • Transform nodes

What is not

• IGSTK Tracker
  • Functionality of using Sockets for sending Tracker data to Slicer

Basic Demo of VTK Sockets

• First, build VTK with Parallel enabled.
• The use the following files:
  • SocketServer.cxx
  • SocketClient.cxx
  • CMakeLists.txt
  • Code now Available in the NAMIC Sandbox
    • http://www.na-mic.org/svn/NAMICSandBox/trunk/IGSTK-Slicer-IntegrationViaSockets/VTKBasicExample/
    • Modified from VTK/Parallel/Testing/Cxx
