The gluOrtho2D function defines a 2-D
orthographic projection matrix.

GLdouble bottom,
|
|
|
GLdouble top |

Parameters
left,
right
The
coordinates for the left and right vertical clipping planes.
bottom,
top

coordinates for the bottom and top horizontal clipping planes.

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