code: public void setCamera(double eyeX, double eyeY, double eyeZ, double centerX,

docs: Sets the position of the camera through setting the eye position, the
  center of the scene, and which axis is facing upward. Moving the eye
  position and the direction it is pointing (the center of the scene)
  allows the images to be seen from different angles.
