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

Syntax

void WINAPI gluOrtho2D(
   GLdouble left,
   GLdouble right,
   GLdouble bottom,
   GLdouble top,
);

Parameters

left: The coordinate for the left vertical clipping plane.
right: The coordinate for the right vertical clipping plane.
bottom: The coordinate for the bottom horizontal clipping plane.
top: The coordinate for the top horizontal clipping plane.

Return value

This function does not return a value.

Remarks

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