title: how to draw sphere using math/sphere.js in threee.js?
body: <p>Drawing the sphere with mesh function.</p>
  
  <pre><code>function DRAW_SP(x,y,z)
  {
      var geometry = new THREE.SphereGeometry( .02, 100,100 );
      var material = new THREE.MeshBasicMaterial( {color: 0xff0000} );
      var sphere = new THREE.Mesh( geometry, material );
      sphere.position.set(x,y,z );
      scene.add( sphere );
  }
  </code></pre>
  
  <p>its working good , but how to draw the same using Sphere.js, given in three.js/doc under math?</p>
  
  <p>i tried like this</p>
  
  <pre><code>var sphere1= new THREE.Sphere(new THREE.Vector3( -l/2, 0, 0 ), 1.0);
  scene.add( sphere1);
  </code></pre>
  
  <p>its not working .. can any one give a simple example to use like this?</p>
