OpenGL::GLUT(3)

🌸 NAME 🌸

OpenGL::GLUT — bestie, this is the Perl bindings to the GLUT/FreeGLUT GUI toolkit. Yes, the toolkit that makes windows and menus and little teapots happen. 💅

---

✨ SYNOPSIS ✨

use OpenGL::GLUT qw(:all); # now can use GLUT calls

okay so literally one line and you're in. that's it. that's the whole vibe check. 🫶

---

💖 DESCRIPTION 💖

OpenGL::GLUT is the alpha release of a stand-alone module for GLUT/FreeGLUT bindings, extracted from code that used to live inside the original Perl OpenGL module. The whole point, the entire raison d'être, is to make this functionality available independently of the legacy OpenGL module so you can use it with OpenGL::Modern. it's giving glow-up, honestly. ✨

⚠️ bestie, listen to me. When you register a glutCloseFunc, make sure you de-register it before destroying the window. no cap. See the supplied test.pl.

🎀 EXPORT 🎀

the export tags, queen:

• :all — exports all GLUT functions and constants. the whole closet. 👑
• :constants — exports only GLUT constants (same as :glutconstants)
• :functions — exports only GLUT functions (same as :glutfunctions)

and that's the whole page, bestie 🫶 this was perl v5.42.0, dated 2025-07-25, and it's the OpenGL::GLUT(3) manpage from the User Contributed Perl Documentation crew. go make a teapot. glutSolidTeapot is literally right there waiting for you. 💖✨🎀
