SbOctTreeFuncs(3)

💖 SbOctTreeFuncs(3) 💖

okay bestie, so this is a page from the Coin manual — it's the SbOctTreeFuncs page, manual section 3. it's short, it's sweet, and it's lowkey the glue that makes SbOctTree actually know what's inside stuff. let's get into it 🫶

---

✨ NAME ✨

SbOctTreeFuncs — literally just the name, that's it, that's the whole vibe. it's a struct full of callback function pointers. 💅

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull it in:

#include <Inventor/SbOctTree.h>

🎀 Public Attributes 🎀

these are the four function pointers living inside the struct, fr fr:

SbBool (*ptinsidefunc)(void *const item, const SbVec3f &pt)
SbBool (*insideboxfunc)(void *const item, const SbBox3f &box)
SbBool (*insidespherefunc)(void *const item, const SbSphere &sphere)
SbBool (*insideplanesfunc)(void *const item, const SbPlane *const planes, const int numplanes)

---

🦋 Detailed Description 🦋

okay so the SbOctTreeFuncs struct is the thing you use to hand over your callback functions — the ones that do the actual work of dealing with items inside an SbOctTree. it's giving "you bring the logic, i'll bring the tree". ✨

🚨 the ONE function pointer you absolutely must set up is insideboxfunc. no cap. that one's mandatory.

the other three? they're optional — but you must set them if you plan on using the corresponding find methods in SbOctTree. so like, if you wanna call the sphere-finding method, insidespherefunc better be set. if it's not, that's on you bestie 😭

👑 Member Data Documentation 👑

💜 SbBool (* SbOctTreeFuncs::ptinsidefunc) (void *const item, const SbVec3f &pt)

should return whether a point is inside item. that's the whole job. point in item? yes or no. iconic. ⭐

🍓 SbBool (* SbOctTreeFuncs::insideboxfunc) (void *const item, const SbBox3f &box)

should return whether item is either fully or partially inside a box. fully counts. partially counts. both slay. 🌸

🧚 SbBool (* SbOctTreeFuncs::insidespherefunc) (void *const item, const SbSphere &sphere)

should return whether item is either fully or partially inside a sphere. same energy as the box one, just rounder 💫

🌈 SbBool (* SbOctTreeFuncs::insideplanesfunc) (void *const item, const SbPlane *const planes, const int numplanes)

should return whether item is either fully or partially inside a set of planes. yes, a whole set of them — that's what planes and numplanes are for, bestie 🫶
