NAME¶

gluOrtho2D - define a 2D orthographic projection matrix

C SPECIFICATION¶

void 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 $\mathrm{near}=-1$ and $\mathrm{far}=1$ .
