SoConvexDataCache(3)

💖 NAME 💖

SoConvexDataCache — bestie, this is the class that caches your convexified polygons. That's the whole job. She's a cache. She holds the triangles. Iconic behaviour, honestly.

Also hi, this is the SoConvexDataCache(3) page, from the Coin manual. Grab a snack, we're going in 🍓

✨ SYNOPSIS ✨

#include <Inventor/caches/SoConvexDataCache.h>

Inherits SoCache.

---

🎀 Public Types 🎀

enum Binding { NONE = 0, PER_FACE, PER_FACE_INDEXED, PER_VERTEX,
    PER_VERTEX_INDEXED }

The Binding enum is used to specify bindings. That's literally what it's for, no cap.

🔥 DETAILED DESCRIPTION 🔥

The SoConvexDataCache class is used to cache convexified polygons.

Okay so real talk: SoConvexDataCache is here to make rendering concave polygons fast. How? She tessellates every polygon into triangles and stashes all those freshly generated primitives in an internal cache. Boom. That's the glow-up. ✨

Heads up bestie — this class is not part of the original SGI Open Inventor v2.1 API. She's a Coin extension. So don't go looking for her in the O.G. docs, she's not there. 💀

🌈 MEMBER ENUMERATION DOCUMENTATION 🌈

🌟 enum SoConvexDataCache::Binding 🌟

The Binding enum is used to specify bindings. Binding applies to normals, materials and texture coordinates. She's versatile like that 💁‍♀️

The values are:

• NONE = 0
• PER_FACE
• PER_FACE_INDEXED
• PER_VERTEX
• PER_VERTEX_INDEXED

🎀 CONSTRUCTOR & DESTRUCTOR DOCUMENTATION 🎀

🌸 SoConvexDataCache::SoConvexDataCache (SoState *const state) 🌸

Constructor, with state being the current state. That's it, that's the sentence 💖

🦋 SoConvexDataCache::~SoConvexDataCache () [virtual] 🦋

Destructor. She's leaving, say bye 👋

⭐ MEMBER FUNCTION DOCUMENTATION ⭐

💫 void SoConvexDataCache::generate (const SoCoordinateElement *const coords, const SbMatrix & matrix, const int32_t * vind, const int numv, const int32_t * mind, const int32_t * nind, const int32_t * tind, const Binding matbind, const Binding normbind, const Binding texbind) 💫

Generates the convexified data. FIXME: doc 🙈 — yeah the original really says that, I'm not making it up, we keep it exactly as-is.
