SCA(nged)

✨ SCA(nged) — the scaling command, bestie edition ✨

Okay so picture this: you're in nged (hey BRL-CAD bestie 👋) and you need something to get bigger or smaller. That's literally what sca is for. It's the BRL-CAD User Commands glow-up moment. 💅

🌸 NAME 🌸

sca — the command you use to apply a scaling factor. That's it. That's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

sca {[sfactor] | [x-sfactor y-sfactor z-sfactor]}

So you either hand it one number, or you hand it three numbers. Choose your fighter. ✨

💖 DESCRIPTION 💖

sca applies a scaling factor to an object or a view. Obsessed.

When you pass it one parameter, an "object or view" gets a uniform scale factor — everything scales together, no favorites. 🌈

When you pass it three parameters, an object gets a unique scale factor applied to each axis — so x, y, and z can each go off and do their own thing. Main character energy per axis, honestly. 👑

And here's the important part, bestie: what actually happens is determined by the Transform option in the Settings menu. So it's normally affected by whatever mode of operation MGED is currently in — like matrix edit, primitive edit, or viewing. Context is everything, iykyk. 🫶

⚠️ Note, and this one matters: three parameters can only be applied in "matrix edit" mode. Otherwise, only scale pipe and tori primitives uniformly — because if you don't, raytracer and other errors may occur. Not cute. Not slay. Just errors. 💀

🔥 EXAMPLES 🔥

These examples show sca doing its thing — applying a scaling factor to an object or a view. Let's go. 🍓

⭐ Example 1. Apply a scaling factor to an object or view.

mged>sca 2

In matrix edit mode, the object being affected will get twice as big. Iconic.

In view mode, the size of the view will be doubled — which means it's showing twice the volume of space, hence making objects appear half their previous size on the display. Yes, that's the plot twist: the view got bigger, so everything in it looks smaller. The math is mathing. 😭✨

💜 Example 2. Apply a scaling factor to an object.

mged>sca 2 1 1

In matrix edit mode, the object being affected will get twice as big along the x-axis. Only the x-axis. She's specific. 🎀
