FORTRAN SPECIFICATION
SUBROUTINE fgluOrtho2D( REAL*4 left,
REAL*4 right,
REAL*4 bottom,
REAL*4 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.
DESCRIPTIONfgluOrtho2D sets up a two-dimensional orthographic viewing region. This
