After accumulating and defining functional joint landmarks, it is necessary to post-process them from the Model Builder's Post-Process feature (click on the Post-Processing icon on the toolbar ).

Defined functional joint landmarks are listed in the top half of the tab. Select the check box for the functional joint to make it active for the rest of the tab. Note The selected F_RHIP landmark was created with an Event Sequence defining the range of frames to be used from the motion trial.

Once you're ready, click on either the “Compute Checked Landmarks” or “Compute ALL Landmarks” button to compute your functional joint landmarks.

It is possible to specify that a file already open in the Workspace can be used for the functional movement, or to load a C3D file from disk. Note that more than one file can be added to the list, but each landmark may only be assigned to one movement trial.

Motion trials need to be selected by checking the check box to be made active.

Alternatively, the user can select a start frame and an end frame for each landmark. The buttons “Set START Event to Current Frame” and “Set START Event to Current Frame” allow the user to play the animation of the movement trial and press the buttons at the appropriate frames. After loading the movement trials, they will appear in the bottom list box. Note that the selected landmark was created with an Event Sequence defining the range of frames of the motion trial to use.

The processing results from a functional will appear as above. First the name and parameters that were specified, then a series of intermediate steps in the algorithm in Visual3D that most people can safely ignore when there are no errors.
