GLUTPOSTREDISPLAY(3)

💖 GLUTPOSTREDISPLAY(3) 💖

okay bestie, pull up a chair, we're talking about glutPostRedisplay — a little function from the OpenGLUT manual, in the window section. it's tiny. it's iconic. it does one job and it does it beautifully. ✨

📚 LIBRARY

OpenGLUT — window stuff 🪟

---

✨ SYNOPSIS ✨

#include <openglut.h>

void
glutPostRedisplay(void);

that's it. no args. no drama. no notes. 💅

---

🦋 DESCRIPTION 🦋

so like, whenever circumstances indicate that your window needs to be redisplayed — and bestie, you will know when — you can call glutPostRedisplay() to tell OpenGLUT that you wanna redraw your graphics. it's basically you raising your hand in class like "hi yes i would like a fresh frame please 🥺".

and here's the tea: multiple calls to this function may be coalesced by OpenGLUT, so it won't spam your drawing support with excessive invocations. like, if you call it five times in a row, OpenGLUT is gonna be like "girl i heard you the first time" and merge them into one. efficient queen behavior. 👑

the ultimate effect of this function? it calls your Display callback for the current window. that's the whole vibe. that's the moment. 🌈

ngl this is the "hey, notice me" of the OpenGLUT world — and yes, it works every single time. fr fr.
