SODECOMPOSEROTATION(3iv)

💖 SoDecomposeRotation(3IV) 💖

okay bestie, buckle up — this is the manual page for SoDecomposeRotation from the <Inventor/engines/SoCompose.h> crew, and it's genuinely so cute once you get it. she takes a rotation and splits it into the two things hiding inside it. that's the whole vibe. slay.

🌈 DESCRIPTION 🌈

okay so picture this: this engine takes a rotation as input, and it decomposes it — splits it apart — into an axis value and a rotation angle. and the angle? it's in radians. periodt. 🔥

and here's the part that's lowkey iconic: the input can hold multiple values, which means the engine can decompose several rotations in parallel. it's giving multitasking queen. she's not doing one rotation at a time, she's doing all of them. obsessed. ✨

---

💜 INPUTS 💜

• SoMFRotation rotation — the rotation that's about to get decomposed, bestie. send her in 🦋

---

💖 OUTPUTS 💖

• (SoMFVec3f) axis — the axis of rotation, derived from the input. that's the "which way are we spinning" of it all 🌸
• (SoMFFloat) angle — the angle (in radians, don't forget) derived from the input. the "how much are we spinning" 🎀

---

🧚 METHODS 🧚

• SoDecomposeRotation() — Constructor. she's born 💫

---

💅 FILE FORMAT/DEFAULTS 💅

DecomposeRotation {
   rotation  0 0 1  0
}

that's the default right there — rotation starting out as 0 0 1 0. as she should. 🍓

go read those too, iykyk, they're all part of the same friend group 🫶

and that's the whole page bestie!! this was SoDecomposeRotation(3IV) from the SoDecomposeRotation(3IV)() manual — go decompose something cute today, mwah 💖💅✨
