title: Three.js - TypeError: THREE.Scene is not a constructor
body: <p>I am just trying out Three.js so I can implement it to a project of mine, however when I run the first example in the documentation:</p>
  
  <pre><code>&lt;html&gt;
      &lt;head&gt;
          &lt;title&gt;My first Three.js app&lt;/title&gt;
          &lt;style&gt;
              body { margin: 0; }
              canvas { width: 100%; height: 100% }
          &lt;/style&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;script src="three.js"&gt;&lt;/script&gt;        
          &lt;script&gt;
              var scene = new THREE.Scene();
              var camera = new THREE.PerspectiveCamera( 75, window.innerWidth/window.innerHeight, 0.1, 1000 );
  
              var renderer = new THREE.WebGLRenderer();
              renderer.setSize( window.innerWidth, window.innerHeight );
              document.body.appendChild( renderer.domElement );
  
              var geometry = new THREE.BoxGeometry( 1, 1, 1 );
              var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
              var cube = new THREE.Mesh( geometry, material );
              scene.add( cube );
  
              camera.position.z = 5;
  
              var render = function () {
                  requestAnimationFrame( render );
  
                  cube.rotation.x += 0.1;
                  cube.rotation.y += 0.1;
  
                  renderer.render(scene, camera);
              };
  
              render();
          &lt;/script&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I get this error:</p>
  
  <blockquote>
    <p>TypeError: THREE.Scene is not a constructor</p>
  </blockquote>
  
  <p>I tried adding scene.js, but it threw another error inside scene.js so it didn't work. I am using version r80 and I heard there was some non-working samples in the documentation, however I am not sure what's wrong here.</p>
  
  <p>Any help would be appreciated.</p>
