💖 SoMFVec2d 💖

okay so bestie, welcome to a page from the Library Functions Manual — section 3, SoMFVec2d(3) — and it's literally just a whole manual about one little class. grab a boba, we're doing this. 🧋✨

🌸 NAME 🌸

SoMFVec2d — the class that is a container for SbVec2d vectors. that's it. that's the whole name section. iconic. 💅

✨ SYNOPSIS ✨

#include <Inventor/fields/SoMFVec2d.h>

Inherits SoMField.

📖 Detailed Description 📖

okay so the SoMFVec2d class is a container for SbVec2d vectors. that's the vibe. 🎀

you use this field anywhere — nodes, engines, or other field containers — that needs to store an array of vectors with two elements. two. elements. per vector. that's the whole thing, no notes. ✌️

this field supports application data sharing through a setValuesPointer() method. head over to the SoMField docs if you wanna know how to actually use that function, bestie, because this page is not gonna spell it out. 🫶

⚠️ okay listen, this part matters: 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 out here porting old SGI code, this one is not gonna be there for you. 💀

🧠 Member Function Documentation 🧠

`SoType SoMFVec2d::getTypeId (void ) const` [virtual]

returns the type identification instance which uniquely identifies the Coin field class the object belongs to. like a little name tag but for types. 🏷️

See also: getClassTypeId(), SoType

Implements SoField.

`void SoMFVec2d::copyFrom (const SoField & f)` [virtual]

copies the value(s) from f into this field. heads up though — f must be of the same type as this field. no mixing, no matching. 🙅‍♀️

Implements SoField.

`SbBool SoMFVec2d::isSame (const SoField & f) const` [virtual]

checks for equal type and equal value(s). both. not one or the other. 👯

Implements SoField.

`void SoMFVec2d::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. (translation: not for you, bestie, it's giving backstage pass energy. 🙈)

Implements SoMField.

`void SoMFVec2d::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. very much a behind-the-scenes situation. 🎬

Implements SoMField.

`const SbVec2d * SoMFVec2d::getValues (const int start) const` [inline]

returns a pointer to the values array. boom. pointer. ✨

`void SoMFVec2d::setValues (int start, int numarg, const double xy[][2])`

set num vector array elements from xy, starting at index start. 📥

`void SoMFVec2d::set1Value (int idx, double x, double y)`

set the vector at idx. just the one. singular. 🎯

`void SoMFVec2d::set1Value (int idx, const double xy[2])`

set the vector at idx. yes it's the same description, yes it's a different signature, no we don't make the rules. 💅

`void SoMFVec2d::setValue (double x, double y)`

set this field to contain a single vector with the given element values. ✨

`void SoMFVec2d::setValue (const double xy[2])`

set this field to contain a single vector with the given element values. (again. different signature. same energy. 🦋)

and that's the whole page, bestie!! this was Coin, Version 3.1.3, and the page you're on is SoMFVec2d(3) — go forth and store your two-element vectors, you absolute icon. 🎀💜🦋✨
