# Method GLU.gluOrtho2D()

Method gluOrtho2D

  `void gluOrtho2D(float left, float right, float bottom, float top)`

Description

  gluOrtho2D sets up a two-dimensional orthographic viewing region. This is equivalent to calling

  glOrtho(left, right, bottom, top, -1.0, 1.0);

FIXME

  The GLU manual says `glOrtho(a,b,c,d, 0, 1)`.
