C SPECIFICATION

       void GLAPIENTRY gluOrtho2D( GLdouble left,
                                   GLdouble right,
                                   GLdouble bottom,
                                   GLdouble top )

PARAMETERS

       left, right Specify  the  coordinates  for  the left and right vertical
                   clipping planes.

       bottom, top Specify the coordinates for the bottom and  top  horizontal
                   clipping planes.

DESCRIPTION

       gluOrtho2D sets up a two-dimensional orthographic viewing region.  This
       is equivalent to calling glOrtho with near=-1 and far=1.
