This tutorial shows you how to generate real time feedback from the Visual3D RealTime Tab when streaming a C3D file through Visual3D. The pictures and example in this tutorial are specific to graphing Left Ankle Angles. However, the same principles can be applied to any Link Model Based items.

1. Download the file model.zip
2. Save the file where you would normally save motion capture files.

These sample Qualysis files were downloaded from C3D.org

1. From the File menul, select Open/Add…, choose model.cmo
2. From the workspace status screen, verify the model file named Standing_Hybrid_2.c3d appears in the column labeled Models/Calibration Files.
   
3. Switch to the Models tab to verify bones in picture
   

1. Open the Real-Time tab
2. Connect to the C3D stream using either:
   1. the Built in RT plugin Click C3DFile_RT (used to emulate a camera system), Browse the dynamic C3D file (Walking_Hybrid_2.c3d), NOTE: Before using the real time stream, users should test using C3D files collected in their lab
      
   2. the External RT plugin, see the instructions on how to run biofeedback through Visual3D server: Visual3D Server Tutorial
      
3. The data is automatically applied to the model

NOTE: Streaming status is in the lower left

1. Open up Model Based Data Computation under the Real-Time Pipeline
2. Double click Compute_Model_Based_Data
3. Click Edit
   
4. Change the corresponding:
   Data Name: Ankle
   Folder: ORIGINAL
   Model Based Item Properties: JOINT_ANGLE
   Segment: Right Foot
   Reference Segment: Right Shank
   
5. Click Done

1. Click Add in the Real-Time Graphs section, and enter the following:
   Data to: LINK_MODEL_BASED::ORIGINAL::Ankle
   
2. Click OK

Your result should show a Real-Time stream that looks like the picture below:
