💖 NAME 💖

okay so, this is SoMFVec2i32(3) from the Coin manual (section 3, bestie, we're in the library pages) — and SoMFVec2i32 is literally just a container for SbVec2i32 vectors. that's the whole vibe. it holds your little 2D integer vectors, and it does it beautifully. 💅

📖 Detailed Description 📖

so SoMFVec2i32 is, again, a container for SbVec2i32 vectors. we said it, we meant it, we're saying it again. 💖

this field is the one you reach for when nodes, engines, or literally any other field container need to hold an array of vectors with two elements. two. not three. don't come at it with a z component, it's not that girl. 🎀

this field supports application data sharing through a setValuesPointer() method. for the full tea on how to actually use that, go read the SoMField documentation. iykyk. ✨

🚨 heads up bestie: be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API. so if you port this somewhere old-school, it will simply not exist. no cap.

🔥 Member Function Documentation 🔥

void * SoMFVec2i32::createInstance (void ) [static]

ngl this API member is considered internal to the library, because it's not likely to be of interest to the application programmer. 🙈

it creates a new instance of the class type corresponding to the SoType object.

SoType SoMFVec2i32::getClassTypeId (void ) [static]

this static method returns the SoType object associated with objects of this class. it's giving ✨type system✨.

SoType SoMFVec2i32::getTypeId (void ) const [virtual]

returns the type identification of an object derived from a class inheriting SoField. this is used for runtime type checking and "downward" casting. very demure, very runtime.

implements SoField.

void SoMFVec2i32::copyFrom (const SoField & f) [virtual]

copy value(s) from f into this field. f must be of the same type as this field — no mixing, bestie, that's the rule. 💅

implements SoField.

SbBool SoMFVec2i32::isSame (const SoField & f) const [virtual]

checks for equal type and value(s). both. it's thorough like that. 🫶

implements SoField.

void SoMFVec2i32::deleteAllValues (void ) [protected], [virtual]

this API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

implements SoMField.

void SoMFVec2i32::copyValue (int to, int from) [protected], [virtual]

this method is used for moving values around internally within a multivalue field. it needs to be overridden in each field so it automatically takes care of running copy constructors where necessary. it's the behind-the-scenes girlie keeping everything organized. 🎀

implements SoMField.

const SbVec2i32 * SoMFVec2i32::getValues (const int start) const [inline]

returns a pointer to the values array. that's it, that's the function. ✨

void SoMFVec2i32::initClass (void ) [static]

internal method called upon initialization of the library (from SoDB::init()) to set up the type system. iconic setup behaviour.

void SoMFVec2i32::setValues (int start, int numarg, const int32_t xy[][2])

set num vector array elements from xy, starting at index start. bulk edit energy. 🔥

void SoMFVec2i32::set1Value (int idx, int32_t x, int32_t y)

set the vector at idx. just the one. singular. main character moment.

void SoMFVec2i32::set1Value (int idx, const int32_t xy[2])

set the vector at idx. same deal, different argument shape. 💜

void SoMFVec2i32::setValue (int32_t x, int32_t y)

set this field to contain a single vector with the given element values. one vector, and it's this one. periodt.

void SoMFVec2i32::setValue (const int32_t xy[2])

set this field to contain a single vector with the given element values. yep, again, just passed as an array this time. 🦋

and that's the whole page, gorgeous. this was Coin version 4.0.10, dated Thu Jun 25 2026 00:00:00, and you just read SoMFVec2i32(3). go forth and store exactly two int32's per vector, you absolute legend 👑✨
