+     *  a three-dimensional display object with a non-zero z-coordinate.
+     *
+     *  <p>A degree close to <code>0</code> means that the screen's two-dimensional x- and y-coordinates are 
+     *  roughly the same as the three-dimensional x-, y-, and z-coordinates with little or 
+     *  no distortion. In other words, for a small angle, a display object moving down the z axis appears
+     *  to stay near the same size and moves little. </p>
+     *
+     *  <p>A value close to <code>180</code> degrees results in a fisheye lens effect: positions 
+     *  with a <code>z</code> value smaller than <code>0</code> are magnified, while positions with a 
+     *  <code>z</code> value larger than <code>0</code> are minimized. With a large angle, a display object
+     *  moving down the z axis appears to change size quickly and moves a great distance. If the field of view
+     *  is set to <code>0</code> or <code>180</code>, nothing is seen on the screen.</p>
