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 near = -1 and far = 1.
