+===== Purpose =====
+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.

+===== Steps =====
-===== preparing for the tutorial =====
+==== Preparing for the Tutorial ====
+  - Download the file //[[https://www.has-motion.com/download/RTtutorials/Qualysis/model.zip|model.zip]]//
+  - Save the file where you would normally save motion capture files.
-  - download the file //[[https://www.has-motion.com/download/rttutorials/qualysis/model.zip|model.zip]]//
+These sample Qualysis files were downloaded from [[https://www.c3d.org/sampledata.html|C3D.org]]
-  - save the file where you would normally save motion capture files.
-these sample qualysis files were downloaded from [[https://www.c3d.org/sampledata.html|c3d.org]]
+==== Step 1 - Open CMO File ====
+  - From the File menul, select **Open/Add...**, choose //model.cmo//
+  - From the workspace status screen, verify the model file named Standing_Hybrid_2.c3d appears in the column labeled Models/Calibration Files. \\ {{:LoadRTModel.jpg?500}}
+  - Switch to the **Models** tab to verify bones in picture \\ {{:RTVerifyBones.jpg?500}}
-===== step 1 - open cmo file =====
+==== Step 2 - Connect to RT stream/Load Emulation ====
+  - Open the //Real-Time// tab
+  - Connect to the C3D stream using either:
+    - 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 \\ {{:RTEmulateCamera.jpg}}
+    - the External RT plugin, see the instructions on how to run biofeedback through Visual3D server: [[https://www.c-motion.com/v3dwiki/index.php/Visual3DServer_Tutorials_Biofeedback_V3DRealtime|Visual3D Server Tutorial]] \\ {{:V3DRealTime_Tutorial_Step4_ConnectToServer.png?500}}
+  - The data is automatically applied to the model
+**NOTE:** Streaming status is in the lower left
-|1. from the file menu, 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.  |  loadrtmodel.jpg|
+==== Step 3 - Compute model based item: RT pipeline ====
+  - Open up //Model Based Data Computation// under the **Real-Time Pipeline**
+  - Double click Compute_Model_Based_Data
+  - Click **Edit** \\ {{:RTPipeline_CMBD.jpg?500}}
+  - Change the corresponding: \\ **Data Name:** Ankle \\ **Folder:** ORIGINAL \\ **Model Based Item Properties:** JOINT_ANGLE \\ **Segment:** Right Foot \\ **Reference Segment:** Right Shank \\ {{:Capture_Model_Based_Data.jpg}}
+  - Click **Done**
-|3. switch to the **models** tab to verify bones in picture\\   |  rtverifybones.jpg|
+==== Step 4 - Create Graph ====
+  - Click **Add** in the **Real-Time Graphs** section, and enter the following: \\ **Data to:** LINK_MODEL_BASED::ORIGINAL::Ankle \\ {{:GraphDef.jpg?500}}
+  - Click **OK**
-\\
+==== Complete ====
+Your result should show a Real-Time stream that looks like the picture below:
