title: Make surface in three.js
body: <p>I have point cloud in 3D. I want make surface in three.js. I added point in Geometry with Vector3.</p>
  
  <pre><code>for(var key in dt)
  {
  var hole = dt[key];
  var pX = hole['x'] - planeMinX;
  var pY = hole['y'] - planeMinY;
  var pZ = hole['z'];
  gPlane.vertices.push(new THREE.Vector3(pX, pY, pZ));
  }
  </code></pre>
  
  <p>How compute faces? Or is there an easier way?</p>
