SOINTERPOLATEVEC4F(3iv)

💖 SoInterpolateVec4f — the 3IV manual, but make it cute 💖

okay bestie, sit down, hydrate, because today we're learning about SoInterpolateVec4f — she's a whole engine and she interpolates 4D floating-point vectors. yes. four of them. and she's from the (3IV) manual, so you know she's vintage-coded and iconic. 🎀

💜 DESCRIPTION 💜

so like, the whole point of this engine is that she linearly interpolates between two 4D vectors, and she does it based on the alpha input value. that's the assignment. that's the job. 🫶

and the alpha value? bestie, she should be between 0.0 and 1.0. that's the range. respect the range. 😤

here's the slay part: the input fields can hold multiple vectors, which means this engine can interpolate several objects in parallel. multitasking queen behavior honestly 👑

one little thing though — one of the inputs may have more values than the other. and when that happens? the last value of the shorter input gets repeated as necessary. so nobody's left hanging, the short one just copies the long one's energy. fr fr. ✨

---

🍓 INPUTS 🍓

• SoMFVec4f input0
• SoMFVec4f input1

the engine linearly interpolates from input0 to input1. that's it, that's the journey, she goes from point A to point B 💫

---

🎀 METHODS 🎀

• SoInterpolateVec4f() — Constructor. she's born. 👶✨

---

🧚 FILE FORMAT/DEFAULTS 🧚

this is what she looks like when you write her out, defaults and all:

InterpolateVec4f {
    alpha   0
    input0  0 0 0 0
    input1  0 0 0 0
}

note that alpha defaults to 0, and both input0 and input1 default to 0 0 0 0. four zeros. zero drama. (okay maybe a little drama.) 💀

and that's the whole page, bestie!! this was SoInterpolateVec4f(3IV)() — source and version 3IV, straight from the manual, mwah 💋 she ate and left no crumbs. go interpolate something. periodt. 💅✨🦋
