<br>
<br>If you viewer has a CameraManipulator attached to it he manipulator
<br>will keep overriding the matrix you set on each frame, simply don't
<br>assigned a CameraManipulator and you should be fine.

<br>> But actually it makes no change to the camera. The cube is still in the center of the screen after run the scene.
