💖 DESCRIPTION 💖

so basically this engine is the main character who computes the bounding box and the center of a scene graph. the scene graph can be defined by a path or by a root node — pick your fighter, bestie 🥊

here's the tea ☕:

• If the path input is not NULL, the bounding box of the graph defined by the path will be computed. ✨
• If path is NULL, but the node input is not NULL, the bounding box is computed on the graph rooted by the node. 🌸
• By default, the two inputs are NULL. 🙈
• If both the inputs are NULL, the outputs are disabled. like, she simply will not speak. 💀

she uses a default viewport region. so if your graph includes screen-based objects (such as SoText2) you can call setViewportRegion() on the engine instance to set up the correct viewport region to use. that's the move, trust 🫶

---

🦋 INPUTS 🦋

• SoSFNode node — defines the graph for which the bounding box is computed. 🌈
• SoSFPath path — alternatively, defines the graph for which the bounding box is computed. she's the alternative route, and honestly? iconic. 💅

---

👑 OUTPUTS 👑

• (SoSFVec3f) min — minimum point of the computed bounding box. the low point, literally. 🍓
• (SoSFVec3f) max — maximum point of the computed bounding box. the high point, and yes she's highkey slaying. 🔥
• (SoSFVec3f) boxCenter — center of the computed bounding box. dead center, no notes. ✨
• (SoSFVec3f) objectCenter — center of the objects in the graph. a whole different center, don't get it twisted. 🧚

💅 METHODS 💅

SoComputeBoundingBox()

Constructor. she's born. 🎀

void setViewportRegion(const SbViewportRegion &vpReg);

Sets the viewport region to use for the bounding box computation. 📐

const SbViewportRegion & getViewportRegion();

Returns the viewport region to use for the bounding box computation. she gives it right back to you, generous queen 👑

---

📄 FILE FORMAT/DEFAULTS 📄

ComputeBoundingBox {
    node  NULL
    path  NULL
}

both NULL by default, meaning she's quiet until you give her something to work with. respectful. 🙈

🌟 SEE ALSO 🌟

SoEngineOutput, SoGetBoundingBoxAction, SbBox3f

go read those too, bestie, they're all in the same friend group 💜

---

a note from your girl: keep the outputs in mind, because if both inputs are NULL you get nothing — outputs disabled, no vibe, no box. set your node or your path first. periodt. 💖

and that's the whole page, babes! this was SoComputeBoundingBox(3IV)() — both the header AND the footer said so, and honestly? consistency is so cute. written under the SoComputeBoundingBox(3IV)() banner, dated with all the love of an unnamed date, and signed off with a kiss 🎀✨💖
