SbOctTreeFuncs(3)

💖 SbOctTreeFuncs 💖

okay bestie, buckle up, this one is from section 3 of the manual (library functions, the good stuff) and it's genuinely so chill. it's a lil struct that holds a bunch of callback function pointers, and it's how you tell an SbOctTree how to vibe-check its items. no cap. 🫶

✨ NAME ✨

SbOctTreeFuncs — the callback squad for your oct tree 🌳

---

🌸 SYNOPSIS 🌸

#include <Inventor/SbOctTree.h>

💜 Public Attributes 💜

• SbBool(* ptinsidefunc )(void *const item, const SbVec3f &pt) — the point-in-item checker 🎯
• SbBool(* insideboxfunc )(void *const item, const SbBox3f &box) — the box checker 📦
• SbBool(* insidespherefunc )(void *const item, const SbSphere &sphere) — the sphere checker 🔮
• SbBool(* insideplanesfunc )(void *const item, const SbPlane *const planes, const int numplanes) — the planes checker ✈️

---

👑 DETAILED DESCRIPTION 👑

so like. the SbOctTreeFuncs struct is literally just a lil container for callback functions, and its whole job is to let you work with items inside an SbOctTree. that's it. that's the gig. 💅

here's the tea though, and this part is important: the only function pointer you're required to set up is insideboxfunc. the others? you set those if — and only if — you're actually planning to use the matching find methods over in SbOctTree. so don't set them for fun, set them because you need them. iykyk. 🎀

🦋 MEMBER DATA DOCUMENTATION 🦋

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

should return whether a point is inside item. that's the whole assignment bestie, just answer the question: is this point in there or not? ⭐

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

should return whether item is either fully or partly inside a box. so partial credit totally counts here, it's not a strict all-or-nothing situation 📦✨

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

should return whether item is either fully or partly inside a sphere. same deal as the box one — partial counts 🔮

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

should return whether item is either fully or partly inside a set of planes. yes, a whole set of them, that's what planes and numplanes are for. go off 🛩️
