====== Example - Functional Hip ======

[[https://www.has-motion.com/download/FunctionalJoints.zip|Sample files]] for this tutorial may be downloaded. \\

1) This tutorial will use the **Static.c3d** and **Functional Hip.c3d** files. \\
2) The Functional Knee.c3d file is used for the [[Visual3D:Documentation:Modeling:Functional_Joints:Example_-_Functional_Knee|Functional Knee Tutorial]]. \\
3) FunctionalJoints_Hip_Knee.cmo contains a static trial with both the functional hip and knee defined. \\
**The calculation of functional joints is described [[Visual3D:Documentation:Modeling:Functional_Joints:Functional_Joints|here]].** \\

==== Define F_RHIP Start and End of motion ====

|1. Select the **START** frame of the right functional movement \\ 1. **Select F_RHIP**, this will highlight the joint in **blue** \\ 2. Using the **slider** (seen below), select the START frame of the right functional movement. //Set the Start Frame to 399// \\ {{:MBAPP_F_RHIP_START_slider.jpg}} \\ 3. Click **Set START Event to Current Frame** | {{:MBAPP_F_RHIP_START.jpg}}|

\\


|2. Select the **END** frame of the right functional movement \\ 1. **Select F_RHIP**, this will highlight the joint in **blue** \\ 2. Using the **slider** (seen below), select the END frame of the right functional movement. //Set the End Frame to 1183// {{:MBAPP_F_RHIP_END_slider.jpg}} \\ 3. Click **Set END Event to Current Frame** \\ | {{:MBAPP_F_RHIP_END.jpg}}|

==== Define F_LHIP Start and End of motion ====

|1. Select the **START** frame of the left functional movement \\ 1. **Select F_LHIP**, this will highlight the joint in **blue** \\ 2. Using the **slider**, select the START frame of the left functional movement. //Set the Start Frame to 1760// 3. Click **Set START Event to Current Frame** \\ | {{:MBAPP_F_LHIP_START.jpg}}|

|2. Select the **END** frame of the left functional movement \\ 1. **Select F_LHIP**, this will highlight the joint in **blue** \\ 2. Using the **slider**, select the END frame of the left functional movement. //Set the End Frame to 2653// \\ 3. Click **Set END Event to Current Frame** \\ | {{:MBAPP_F_LHIP_END.jpg}}|

===== Compute Landmarks =====

|1. Select **Compute ALL Landmarks** \\ 2. **Close** the Model Builder Advanced Post Processing dialog box \\ 3. The **F_RHIP and F_LHIP** landmarks should appear in purple in the 3D viewer \\ **If the landmarks do NOT appear in the 3D viewer, check:** \\ - That the landmarks are turned on (3D View Options) \\ - Check that all steps in this tutorial were completed \\ | {{:F_RHIP_F_LHIP.jpg}}|
