-Tutorial #2 has two main objectives: +In **Tutorial 1**, we used a standing calibration file to define the various bones of a subject's lower body and in effect "built" a 3D model of the subject in the computer's 2D "world". In this tutorial, we will use Visual3D to assign the tracking data of a movement trial to the 3D model to create an animated representation of the subject's lower torso.

 +==== Objectives ====
 +This tutorial has two main objectives. First, to teach users how to assign a movement trial to a model and next, to introduce users to working with C3D data files.
  
  
  
- +==== Preparing for the Tutorial ==== 
-==== Overview ==== +The files needed and end results of this tutorial is available at the following link: [[https://has-motion.com/download/YouTubeTutorial/Visual3D Tutorial 2 Visualizing Data.zip|Visual3D Tutorial 2 Sample Data]]. The following files are present within: 
- +  * **Tutorial2_VisualizingData_Start**: CMZ Workspace file with Lower Body Static Model loaded in. 
-In **Tutorial 1**, we used a standing calibration file to define the various bones of a subject's lower body and in effect "built" a 3D model of the subject in the computer's 2D "world". In this tutorial, we will use Visual3D to assign the tracking data of a movement trial to the 3D model to create an animated representation of the subject's lower torso. +  * **Walking Trial 1.c3d**: Movement trial file to be added to workspace. 
- +  * **Corrected Walking Trial 1.c3d**: Corrected movement trial file.
-=== Preparing for the Tutorial === +

-  - Download the movement trial file [[https://www.has-motion.com/download/examples/Walking%20Trial%201.c3d|Walking Trial 1.c3d]] +
-  - Save the file where you would normally save motion capture files.\\ +
-**Note:** The file [[https://has-motion.com/download/YouTubeTutorial/Visual3D_Tutorial2_SignalProcessing.zip|Visual3D Tutorial 2 Sample Data]] contains the files needed and end results of this tutorial. It may be useful as a secondary resource for verifying your progress.+
  
 ===== Loading the Files ===== ===== Loading the Files =====
- +If it is not already loaded, open the starting cmz file (Tutorial2_VisualizingData_Start). \\ **Note:** CMZ is the file extension Visual3D uses to save your workspace.

   - The data file has now been corrected but the workspace has not been updated so the segment will not appear. To get the missing segment to reappear you need to get Visual3D to recalculate the model. There are 2 ways to do this in Visual3D. You can click the **RECALC** button {{:recalcButton.jpg}} on the toolbar or force the recalculation by switching to the **Model Building** tab and clicking **Build Model.** When the recalculation is complete the 3D figure will now display the missing foot. \\ {{:Tutorial2_7.jpg}}   - The data file has now been corrected but the workspace has not been updated so the segment will not appear.
