fgluOrtho2D(3G)

NAME
     fgluOrtho2D - define a 2D orthographic projection matrix


FORTRAN SPECIFICATION
     SUBROUTINE fgluOrtho2D( REAL*4 left,
                             REAL*4 right,
                             REAL*4 bottom,
                             REAL*4 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
     fgluOrtho2D sets up a two-dimensional orthographic viewing region. This
     is equivalent to calling glOrtho with near = -1 and far = 1.
