SOINTERPOLATEFLOAT(3iv)

💖 NAME 💖

SoInterpolateFloat — bestie, this engine interpolates floating-point values. That's it. That's the whole vibe. ✨

And psst, the manual page itself is called SoInterpolateFloat(3IV) if you ever need to look it up, iykyk. 🎀

🌸 INHERITS FROM 🌸

It's giving very much a lineage moment, okay:

SoBase > SoFieldContainer > SoEngine > SoInterpolate >
SoInterpolateFloat

So it's an SoInterpolate, which is an SoEngine, which is an SoFieldContainer, which is an SoBase. The whole family tree ate. 👑

🦋 DESCRIPTION 🦋

okay so picture this. This engine linearly interpolates between two floating-point values, and it does it based on the alpha input value. That's the whole plot. 💅

The alpha value should be between 0.0 and 1.0. No cap. 📏

Here's the fun part though — the input fields can have multiple values, which means the engine can interpolate several objects in parallel. Multitasking queen behavior. 👑

One of the inputs may have more values than the other. And in that case? The last value of the shorter input gets repeated as necessary. It's literally just stretching. No drama. 🫶

---

🎀 INPUTS 🎀

• SoMFFloat input0
• SoMFFloat input1

The engine linearly interpolates from input0 to input1. That's the journey. The character arc. From point A to point B. 🌈

---

💜 METHODS 💜

• SoInterpolateFloat() — Constructor. It's the birth. The origin story. ✨

---

⭐ FILE FORMAT/DEFAULTS ⭐

Here's what the defaults look like when they're just sitting there being all defaulty:

InterpolateFloat {
    alpha   0
    input0  0
    input1  1
}

Notice alpha starts at 0, input0 starts at 0, and input1 starts at 1. So out of the box it's like… already living its best interpolated life. 🍓

and that's the whole page!! 🎉 this lil doc lives under the title SoInterpolateFloat(3IV), and the footer tag on it is SoInterpolateFloat(3IV)() — so like, if you're out here citing your sources, that's the one. mwah. 💋 no notes. periodt. 💅✨
