title: Calculating normals, indices and UV coordinates for marching cubes mesh
body: <p>I'm following this article:</p>
  
  <p><a href="http://paulbourke.net/geometry/polygonise/" rel="nofollow">http://paulbourke.net/geometry/polygonise/</a></p>
  
  <p>However source code provided generates only triangles.</p>
  
  <p>How can I calculate normals, indices and UV coordinates?</p>
