- <p>\r
- This application illustrates the use of the <a href="3dTrackerFilter.htm">Tracker3DFilter</a>\r
- to perform multi-camera 3D tracking. The intention with this application \r
- is to provide a straightforward example of the use of \r
- Tracker3dFilter in a Windows MFC application. The program \r
- serves a second purpose as well in it's ability to log results from \r
- the tracker to a file for testing or debugging. The details of \r
- configuring the Tracker3dFilter for operation are discussed further \r
- in the document describing the Filter and it's property page. \r
- Here we will deal specifically with the demonstration application.</p>\r
- <p>\r
- The initial configuration of the application is \r
- specified via a series of command line arguments:\r

- <P>When the application runs it will open one video render window for \r
- each camera attached to the Tracker3dFilter in the DirectShow graph \r
- specified on the command line. There will also be a control panel \r
- dialog which provides access to the tracker parameters, allows \r
- calibration of the cameras and displays the tracking results. The \r
- layout and function of this dialog is presented below.</P>\r
