💖 SoSFVec2b 💖

okay bestie so this is a page from the Coin manual, and the star of the show is a class called SoSFVec2b — a lil container that holds exactly one SbVec2b vector. that's the whole vibe. let's get into it ✨

🌸 NAME 🌸

SoSFVec2b — the class that is literally just a container for an SbVec2b vector. one field, one vector, two elements, iconic behavior 💅

✨ SYNOPSIS ✨

#include <Inventor/fields/SoSFVec2b.h>

it inherits from SoSField 🫶

💅 Detailed Description 💅

so SoSFVec2b is a container for an SbVec2b vector, fr fr. that's the whole personality 💖

you'd reach for this field when a node, an engine, or literally any other field container needs to hold a single vector with two elements. one vector. two elements. no notes ✨

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're porting somewhere old-school, she's not coming with you 😭

Coin 2.5 🎀

🔥 Member Function Documentation 🔥

void * SoSFVec2b::createInstance (void ) [static]

okay so this one is considered internal to the library, like it's not really likely to be of interest to the application programmer. it creates a new instance of the class type corresponding to the SoType object. iykyk 🫶

SoType SoSFVec2b::getClassTypeId (void ) [static]

this static method hands you back the SoType object associated with objects of this class. classic ⭐

SoType SoSFVec2b::getTypeId (void ) const [virtual]

returns the type identification of an object derived from a class inheriting SoField. this is what powers runtime type checking and that "downward" casting moment 💅

implements SoField.

void SoSFVec2b::copyFrom (const SoField & f) [virtual]

copies the 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 SoSFVec2b::isSame (const SoField & f) const [virtual]

checks for equal type and value(s). simple as that ✨

implements SoField.

void SoSFVec2b::initClass (void ) [static]

internal method that gets called when the library initializes (from SoDB::init()) so it can set up the type system. behind-the-scenes queen 👑

void SoSFVec2b::setValue (int8_t x, int8_t y)

sets the value of the vector. 💖

void SoSFVec2b::setValue (const int8_t xy[2])

sets the value of the vector. 💖 (yes, again — this is the int8_t xy[2] flavor, not the x, y flavor, and both are valid, slay)

generated automatically by Doxygen for Coin, straight from the source code. not me getting auto-generated by a documentation tool, that's so real 🫶

and that's the whole page, bestie! this lil doc is Version 4.0.10 and it's dated Thu Jun 25 2026 00:00:00 — and it's the manual page for SoSFVec2b(3). periodt 💅✨
