title: Difference between X3D and X3DV files
body: <p>I'm wondering what's the difference between an X3D file and an X3DV file.</p>
  
  <p>I'm creating an application in Java that loads and displays an X3DV file called <code>test.x3dv</code> and I have multiple X3D models that I want to be loaded and I'm using Xj3D.</p>
  
  <p>However, it only want's to load X3DV models. So I was wondering what the differences are, so that I can change the X3D files I have round to be X3DV files.</p>
