 +This is the first tutorial in the Visual3D typical processing session, each of the tutorials will go over the sequence of steps involved in handling and analyzing data in the application. This specific tutorial will go over building a 6 DoF Model from a motion capture dataset.
 +
 +</p><p>The techniques learned here will be consistent with all Visual3D models. However <b>the model described in this tutorial is only designed to illustrate the principles of model building and should not be considered the Default Visual3D lower-body model</b>. Once the user learns the basics of building models, it is up to them to decide what model and marker set is most appropriate for their analyses.
 +</p><p>If you prefer, a video tutorial is available outlining the same process. It is available at this link: <a target="_blank" rel="nofollow noreferrer noopener" class="external text" href="https://youtu.be/bJ6FIICiu8s?feature=shared">Visual3D Video Tutorial 1: Building a 6 DOF Model</a>.
 +</p><p>There are 6 basic steps to performing an analysis of motion capture data in Visual3D:
 +</p>
 +<ol><li>Create a model of your subject using a standing trial and define the linked segments</li>
 +<li>Explore your movement trials, and associate them with your model</li>
 +<li>Perform any signal and event processing required</li>
 +<li>Define any biomechanical model-based calculations (joint angles, moments, powers, etc.)</li>
 +<li>Generate the desired reports</li>
 +<li>If desired, export data for statistical processing</li></ol>
 +<p>In this tutorial we will:
 +</p>
 +<ol><li>Load a standing calibration trial</li>
 +<li>Define various segments to create a lower-body a gait model.</li></ol>
 +<h2><span class="mw-headline" id="Key_Concepts">Key Concepts</span></h2>
 +<p>A <b>calibration file</b> (often referred to as a <b>Standing Trial</b> or a <b>Static Trial</b>) is a short motion capture of the subject in a stationary pose. Marker positions are averaged automatically over all frames to compensate for noise in the data. <b>NOTE:</b> If the subject moved during the standing trial, you can specify a subset of frames using the </html>[[visual3d:documentation:definitions:static_trial|Modify Frame Range For Static Calibration]]<html> command from the <b>Model</b> Menu items.<br>

 +<h3><span class="mw-headline" id="Creating_the_Pelvis_Segment">Creating the Pelvis Segment</span></h3>
 +<p>There are many possible markers for a pelvis segment that make sense anatomically, and have a history in the biomechanics community. Visual3D offers 3 default pelvis segments:
 +</p><p>1) </html>[[visual3d:documentation:modeling:segments:visual3d_pelvis|Visual3D Pelvis]]<html> - The default pelvis segment in Visual3D is labeled a Visual3D Pelvis since the pelvis can be constructed as any other segment. Visual3D inherited this definition from MOVE3D (the precursor software to Visual3D) and has been used by the staff in the Physical Disabilities Branch at the NIH for more than 20 years.
 +</p><p>2) </html>[[visual3d:documentation:modeling:segments:coda_pelvis|CODA Pelvis]]<html> - The CODA pelvis defines the location of the Hip Joint Centers using regression equations from the <a href="https://has-motion.com/wiki/doku.php?id=visual3d:documentation:modeling:segments:coda_pelvis#hip_joint_landmarks" title="Coda Pelvis">Bell and Brand</a> articles.
