SoPointDetail(3)

💅 SoPointDetail — from the Library Functions Manual ✨

okay bestie, sit down, hydrate, and let me tell you about SoPointDetail 💖

🌸 NAME 🌸

SoPointDetail — the class that's literally just here to store detailed info for one single 3D point. one point. that's her whole job. and she does it flawlessly 🎀

👑 Detailed Description 👑

SoPointDetail is for storing detailed information for a single 3D point. that's the vibe. that's the assignment. she ate 💅

Instances of this class get used for, like, a bunch of things — among them storing info about the vertices of lines and polygons after pick operations, and storing info that gets handed back to tessellation callbacks. she's popular, she's booked, she's everywhere 🦋

What's actually inside her? Indices into the vertex coordinate sets, plus indices into material, texture and normal coordinates for the point. so basically a little index girlie with range 💖

🎀 Constructor & Destructor Documentation 🎀

✨ SoPointDetail::SoPointDetail (void )

Sets up an empty detail instance — and by "empty" I mean all indices are equal to 0. blank slate, fresh start, main character origin story 🌸

✨ SoPointDetail::~SoPointDetail () [virtual]

Destructor. she's logging off, no cap 💀

---

💖 Member Function Documentation 💖

✨ SoType SoPointDetail::getTypeId (void ) const [virtual]

Returns the type identification of a detail derived from a class inheriting SoDetail. This is what you use for run-time type checking and "downward" casting. iykyk 🔥

Usage example:

void fuhbear(SoDetail * detail)
{
  if (detail->getTypeId() == SoFaceDetail::getClassTypeId()) {
    // safe downward cast, know the type
    SoFaceDetail * facedetail = (SoFaceDetail *)detail;
  }
  return; // ignore if not a SoFaceDetail
}

For application programmers wanting to extend the library with new detail classes: this method needs to be overridden in all subclasses. not optional bestie, it's giving mandatory 🫶 This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubDetail.h: SO_DETAIL_SOURCE and SO_DETAIL_INIT_CLASS.

Implements SoDetail.

✨ SoDetail * SoPointDetail::copy (void ) const [virtual]

Return a deep copy of ourself. clone her, she's iconic 👑

⚠️ Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you must make sure that both the Coin DLL and the application executable is using the same instance of a C Run-Time (CRT) library. Otherwise, you will get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes. 😭 no fr fr this one is not a drill, respect the CRT rule.

Implements SoDetail.

✨ int SoPointDetail::getCoordinateIndex (void ) const

Returns the index into the coordinate set for the point's 3D coordinates ✨

✨ int SoPointDetail::getMaterialIndex (void ) const

Returns the point's index into the set of materials 🎨

✨ int SoPointDetail::getNormalIndex (void ) const

Returns the point's index into the set of normals 📐

✨ int SoPointDetail::getTextureCoordIndex (void ) const

Returns the point's index into the set of texture coordinates 🧚

✨ void SoPointDetail::setCoordinateIndex (const int idx)

Used by client code for initializing the point detail instance. you're setting it, bestie, own it 💅

✨ void SoPointDetail::setMaterialIndex (const int idx)

Used by client code for initializing the point detail instance. same energy, different index 🍓

✨ void SoPointDetail::setNormalIndex (const int idx)

Used by client code for initializing the point detail instance. normal behaviour, actually 🌈

✨ void SoPointDetail::setTextureCoordIndex (const int idx)

Used by client code for initializing the point detail instance. last one, and she slayed ⭐

and that's the whole page, bestie — thanks for reading all the way to the end, you're a real one 💜 this iconic little manual page ships with Coin, Version 3.1.3, and yes, the page itself is called SoPointDetail(3). go forth and index some points ✨🎀
