title: Camera following an objects rotation
body: <p>I'm trying to get a 'chase' camera working on an object.</p>
  
  <p>I've found an example that doe exactly what I want, however it is aimed at r49:</p>

  <p>I've attempted to update it to the new rotation methods as follows:</p>
  
  <p><code>
     var rotation_matrix = new THREE.Matrix4().makeRotationZ(rotateAngle);
     cube.matrix.multiplySelf(rotation_matrix);
     cube.rotation.setEulerFromRotationMatrix(cube.matrix);
  </code></p>
  
  <p>This seems to work fine for the object, however the camera doesn't follow in the same way. I've put up a demo here:</p>

  <p>(Press A and D to rotate)</p>
  
  <p>What am I doing wrong?</p>
