GLUORTHO2D(3G)GLUORTHO2D(3G)NAMEgluOrtho2D - 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.
DESCRIPTIONgluOrtho2D sets up a two-dimensional orthographic viewing region. This
is equivalent to calling glOrtho with near=−1 and far=1.
