GLUORTHO2D(3G)

GLUORTHO2D(3G) 💖

okay bestie, so this one lives in the GLU part of the OpenGL manual — section 3G, library functions, you know the vibe ✨

---

🌸 NAME 🌸

gluOrtho2D — define a 2D orthographic projection matrix 🎀

---

✨ C SPECIFICATION ✨

void gluOrtho2D( GLdouble left,
                 GLdouble right,
                 GLdouble bottom,
                 GLdouble top )

---

🦋 PARAMETERS 🦋

• left, right — these two are the coordinates for the left and right vertical clipping planes. so like, the walls on your left and your right 🫶
• bottom, top — and these are the coordinates for the bottom and top horizontal clipping planes. floor and ceiling energy 💅

---

💖 DESCRIPTION 💖

gluOrtho2D sets up a two-dimensional orthographic viewing region. no perspective drama, no vanishing point nonsense, just flat and honest 🌸

and here's the tea: it's equivalent to calling glOrtho with near=−1 and far=1. that's literally it, that's the whole thing 💀

lowkey iconic that you don't even have to pass near and far yourself — the function just fills them in for you ✨
