  Z-buffer
       
           An {array} used to store the maximum Z {coordinate}
          of any feature plotted at a given (X, Y) location on the
          screen, used for {hidden line removal} in a 2D rendering of a
          3D scene.  The Z axis is perpendicular to the screen with


          values increasing toward the viewer so that any point whose Z
          coordinate is less than the corresponding Z-buffer value will
          be hidden behind some feature which has already been plotted.
