title: What's the difference between GLSL and c?
body: <p>I have three questions here:</p>
  
  <ol>
  <li>Is the Qt/3D API implemented by GLSL code?</li>
  <li>Is GLSL code compiled and linked as normal c/c++ code, and can it run on CPU (not GPU)?</li>
  <li>Why GLSL is better at rendering than normal c/c++?</li>
  </ol>
