🌸 DESCRIPTION 🌸

okay so listen. This engine has inputs that specify values for translation, rotation, scale, and center of transformation. As output, it produces a transformation matrix that transforms objects into the space specified by the scale, rotation, and translation inputs — and yes bestie, in that order. scale first, then rotation, then translation. write that down. 📝

The input fields can have multiple values, which lets the engine compose several matrices in parallel — like a lil matrix factory line, we love a multitasking queen. 💅 Some inputs may have more values than others. In that case, the last value of the shorter inputs will be repeated as necessary. so nobody's left out, fr fr. 🫶

🦋 INPUTS 🦋

• SoMFVec3f translation — translation in x, y, and z. aka where u slidin' 🛝
• SoMFRotation rotation — rotation. the spin, the twirl, the vibe. 🌀
• SoMFVec3f scaleFactor — scale factors in x, y, and z. how big or smol u feeling today. 🍓
• SoMFRotation scaleOrientation — rotational space for scaling. it's the dedicated zone for scale rotation. ✨
• SoMFVec3f center — center point for scaling and rotating. the main character anchor point. 👑

---

⭐ OUTPUTS ⭐

• (SoMFMatrix) matrix — transformation matrix that transforms from object space into the space specified by the inputs. it's giving glow-up from one space to another. 💖

---

💅 METHODS 💅

• SoComposeMatrix() — constructor. that's it, that's the method. short and slay. 🎀
