====== Create a Functional Joint at the Right Hip ======

This example tutorial provides an overview of the process for creating functional joints. The [[visual3d:documentation:modeling:functional_joints:functional_joints#algorithms_for_calculating_functional_joints|general process]] is illustrated by defining a functional joint for the right hip, e.g., the joint between the Pelvis (RPV) and Right Thight (RTH) segments.

===== Static File =====

  - Load a static .c3d file into the workspace \\ {{:LoadStatic_ModelsTab.jpg?500}}

===== Creating the Functional Joint =====

  - Create the F_RHIP
    - In the **Models Tab**
    - Click the **Landmarks Button**
    - Select the **Functional Tab**
    - Select F_RHIP from the dropdown
    - Click **Create** \\ {{:FunctionalJointTab_FRHIP.jpg?500}}
   - Select tracking targets
     - RPV targets
     - RTH targets
     - Click **Build Model Close**
     - Close tab \\ {{:FRHIP_TrackingTargets.jpg?500}}

===== Post-Processing =====
   - Click Post Processing Button \\ {{:Toolbar_PostProcessing.jpg?500}}
   - In Post Processing dialog
     - Open motion trial
     - Select motion trial (when selected it should be higlighted in blue) \\ {{:ModelBuilderAdvancedPostProcessing_AddMotionFile.jpg?500}}
   - Specify Start Frame
     - Find the start frame of the functional activity using the blue slider on the bottom
     - Select the functional landmark (when selected it should be highlighted in blue)
     - Click Set START Event to Current Frame \\ {{:Toolbar_PostProcessing_StartFrames.jpg?500}}
   - Specify End Frame
     - Find the end frame of the functional activity using the blue slider on the bottom
     - Select the functional landmark (when selected i should be higlighted in blue)
     - Click Set END Event to Current Frame \\ {{:Toolbar_PostProcessing_EndFrames.jpg?500}}
   - Click Compute All Landmarks
   - Results will pop up
   - Click OK
   - Close the dialog box

===== Finish =====
   - The functional right hip landmark should appear in the 3D viewer
