title: What glm::normalize does?
body: <p>I trying to write an MD5 loader in Java from C++ source but I cannot find out what is this line doing:</p>
  
  <pre><code>animatedJoint.m_Orient = glm::normalize(animatedJoint.m_Orient);
  </code></pre>
  
  <p>where the <code>animatedJoint.m_Orient</code> is <code>vec4</code>. What does it do?</p>
