= 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.

= Two types of Modules =

===Normal module===
Each node of modules has event handling functions to put, pull and process data,
and these are called whenever corresponding events occure.
Therefore, the timing of processing is detemined only by NaviTrack events.

===Thread module===
In some application, a module has to call certain procedures
with its own timing, e.g. monitoring hardware, acquiring data from a device.
For this purpose, NaviTrack allows us to create a module with
threading capability. The structure of thread module will be
described later.
