okay bestie, listen, this is the tea from the 3IV manual section — sit down, grab a strawberry, we're doing math but make it fashion 🍓✨

💜 DESCRIPTION 💜

okay so picture this: this engine takes two inputs. one is a vector before a rotation got applied, and the other is that same vector after the rotation happened. and then — plot twist — it hands you back the rotation value that would make the first vector transform into the other one. like, it reverse-engineers the glow-up. it's giving detective energy 🔍✨

and because one rotation is simply never enough, the input fields can hold multiple values, so the engine can compose several rotations in parallel. slay. but here's the fine print, bestie: some inputs might have more values than others. when that happens, the shorter inputs just repeat their last value as many times as needed. no cap, that's literally the rule 🫶

---

🔥 INPUTS 🔥

• SoMFVec3f from — the vector from before the rotation. the "before" pic 📸
• SoMFVec3f to — the vector from after the rotation. the "after" pic, the glow-up, the main character reveal 💅

---

🌈 OUTPUTS 🌈

• (SoMFRotation) rotation — a rotation that transforms one vector into another. the answer. the moment. the reveal 👑

---

⭐ METHODS ⭐

• SoComposeRotationFromTo() — the constructor. it exists, it's doing its little thing, iconic 🎀

---

🦋 FILE FORMAT/DEFAULTS 🦋

ComposeRotationFromTo {
    from  0 0 1
    to    0 0 1
}

both default to 0 0 1 because starting from zero is a vibe 🙈

bestie real talk: nothing here is deprecated or dangerous, it's just an engine doing rotation math, so you're safe. go off 💖
