 The definition of the functional joints can be saved in an INI file for future use, but it is more common to simply save the Model Template because the functional joint definitions (and digitized point definitions) will automatically be saved to the template. The Visual3D template will actually contain two versions of the functional joints. The first is the actual definition, and the second is the resulting explicit value that results from the functional joint computation. This second landmark is the one that is displayed in the viewer and can be used to define a segment or other landmarks. The definition of the functional joints can be saved in an INI file for future use, but it is more common to simply save the Model Template because the functional joint definitions (and digitized point definitions) will automatically be saved to the template.

 Regardless of whether the user selects Targets or Segments, Visual3D creates a technical coordinate system (TCS) to represent each segment for the computations. This is done to ensure that a segment exists because it is possible that the segment definition depends on the functional joint being computed. Regardless of whether the user selects Targets or Segments, Visual3D creates a technical coordinate system (TCS) to represent each segment for the computations.

 If the resulting landmark is defined relative to a segment, Visual3D transforms the landmark from the TCS into the Segment Coordinate System. If the resulting landmark is defined relative to a segment, Visual3D transforms the landmark from the TCS into the Segment Coordinate System.
