✨ ACOS — the arccosine bestie ✨

okay so welcome to ACOS(3G), the 3G manual page, and honestly? she's short, she's sweet, she's giving trigonometry main character energy. 💅 let's get into it.

🌸 NAME

acos — return the arccosine of the parameter 🎀

📜 DECLARATION

here's the signature, no cap, exactly as written:

genType acos(genType x);

🫶 PARAMETERS

  • x — specify the value whose arccosine to return. that's it, that's the whole input, she's simple like that ✨

💖 DESCRIPTION

atan returns the angle whose trigonometric cosine is $x$.

ngl bestie, the page really does say atan right there 👀 i'm just the messenger, i'm not editing the source, i'm not "fixing" it, i'm literally reading it to you. periodt.

the range of values returned by acos is $[0,\pi]$ 🌈

⚠️ and the result is undefined if $\left| x \right| > 1$. that's not a vibe, that's a warning. keep your input inside the club, okay? 💀

👑 VERSION SUPPORT

so there's a whole table in the original about which OpenGL Shading Language versions support this function, and the answer is… all of them. iconic behaviour fr fr. the columns are 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 4.30, 4.40, and 4.50, and acos gets a ✔ in every single one 🎀✨
