NaviTrack Tutorial:Creating module:Module structure

Three types of nodes

• Sink nodes (XxxxSink.h, [XxxxSink.cxx])
  • Leaves in the graph and receive their data values from external sources, such as Polaris optraciking system, and send put the data into NaviTrack data flow graph.

• Source nodes (XxxxSource.h, [XxxxSource.cxx])
  • Leaves to propagate their data values received from other nodes to external outputs.

• Filter nodes (we don't use this in the tutorial)
  • Intermediate nodes and modify the values received from other nodes.
