title: How to turn off animation in three.js
body: <p>While testing code in three.js, animation is not needed.  I can see the first rendered frame.  This would use less power, and stop the fan on the laptop from kicking in as the graphics card heats up.</p>
  
  <p>The examples in three.js have the following structure:</p>
  
  <pre><code>function init() {
    animate()
  }
  
  function animate() {
      requestAnimationFrame( animate );
      render();
      targetRotation = targetRotationOnMouseDown + ( mouseX - mouseXOnMouseDown ) * 0.05;
  }
  
  function render() {
      group.rotation.y += ( targetRotation - group.rotation.y ) * 0.05;
      renderer.render( scene, camera );
  }
  </code></pre>
  
  <p>I do not see how to turn off the repeated calls to animate.
  Is there any easy way to turn off animation?</p>
