INVERSE(3G)

💖 INVERSE(3G) 💖

okay bestie, welcome to the inverse page — a lil function from the 3G manual section that literally just hands you the inverse of a matrix. no drama. well, almost no drama, there's a caveat, we'll get there. 🦋

---

✨ NAME ✨

inverse — calculate the inverse of a matrix 💅

---

🌸 DECLARATION 🌸

here's the whole squad, every single overload, no cap:

mat2 inverse(mat2 m);

mat3 inverse(mat3 m);

mat4 inverse(mat4 m);

dmat2 inverse(dmat2 m);

dmat3 inverse(dmat3 m);

dmat4 inverse(dmat4 m);

---

🎀 PARAMETERS 🎀

• m — the matrix you want the inverse of. that's it. that's the whole parameter. give it a matrix and it does its lil thing 🫶

---

💜 DESCRIPTION 💜

inverse returns the inverse of the matrix m.

⚠️ BIG caveat, pay attention bestie: the values in the returned matrix are undefined if m is singular or poorly-conditioned (aka nearly singular). like, undefined undefined. don't come crying to me. 😭 singular matrices are the enemy fr fr.

⭐ VERSION SUPPORT ⭐

(the original had a whole giant table here — we're doing it as lists because tables are not the vibe today, but every single checkmark and dash is here, i promise 💖)

inverse (float) — OpenGL Shading Language version support:

• 1.10 — - 🙈
• 1.20 — - 🙈
• 1.30 — - 🙈
• 1.40 — ✔ ✨
• 1.50 — ✔ ✨
• 3.30 — ✔ ✨
• 4.00 — ✔ ✨
• 4.10 — ✔ ✨
• 4.20 — ✔ ✨
• 4.30 — ✔ ✨
• 4.40 — ✔ ✨
• 4.50 — ✔ ✨

inverse (double) — OpenGL Shading Language version support:

• 1.10 — - 🙈
• 1.20 — - 🙈
• 1.30 — - 🙈
• 1.40 — - 🙈
• 1.50 — - 🙈
• 3.30 — - 🙈
• 4.00 — ✔ ✨
• 4.10 — ✔ ✨
• 4.20 — ✔ ✨
• 4.30 — ✔ ✨
• 4.40 — ✔ ✨
• 4.50 — ✔ ✨

so like, float inverse showed up in 1.40 and has been thriving ever since, and double inverse didn't pull up until 4.00. late bloomer icon behavior honestly 👑

and that's the whole page bestie, ty for reading, mwah 💋 this was [FIXME: source], dated 01/03/2018, and it lives under the name INVERSE(3G) — slay, periodt, go invert something (that isn't singular) 🎀✨
