title: How to edit the vertices of Mesh in box geometry using three.js?
body: <p>If I have a cube then how can I change its vertices:</p>
  
  <pre><code>var material = new THREE.MeshBasicMaterial( {color: 0xce8b11, transparent: true} );
  var geometry = new THREE.BoxGeometry( 200, 400, 20 );
  var cube = new THREE.Mesh( geometry, material );
  cube.position.x = 300;
  cube.position.y = 300;
  scene.add( cube );
  </code></pre>
