title: WebGL Framework
body: <p>I'm planning to write a 3D FPS game, based on WebGL. </p>
  
  <ul>
  <li>Should I use some WebGL framework? </li>
  <li>What is the most active and popular WebGL library today? Does it support LOD, Heightmaps, COLLADA and some Materials system?</li>
  </ul>
  
  <p>Thanks.</p>
