✨ Detailed Description ✨

So SoMFVec2d is, no cap, a container for SbVec2d vectors. 🫶

You reach for this field whenever nodes, engines, or other field containers need to hold onto an array of vectors with two elements. Two elements, that's the whole personality. 💅

This field is also lowkey a data-sharing girlie: it supports application data sharing through a setValuesPointer() method. Head over to the SoMField documentation for the tea on how to actually use that function. 🍓

SbVec2d, SoSFVec2d

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. Don't go looking for it there, she's not there. 💀

💜 Member Function Documentation 💜

void * SoMFVec2d::createInstance (void ) [static]

Okay so this one is considered internal to the library — it's not likely to be of interest to the application programmer, so don't stress about it. 🙈

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

SoType SoMFVec2d::getClassTypeId (void ) [static]

This static method hands you back the SoType object associated with objects of this class. ✨

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

Returns the type identification of an object derived from a class that inherits SoField. You use this for runtime type checking and "downward" casting, iykyk. 🎀

Implements SoField.

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

Copies the value(s) from f into this field. Bestie, f must be of the same type as this field, no exceptions. 💅

Implements SoField.

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

Checks for equal type and value(s). Simple as that. ✅

Implements SoField.

void SoMFVec2d::deleteAllValues (void ) [protected], [virtual]

This API member is considered internal to the library — not likely to be of interest to the application programmer. 🙈

Implements SoMField.

void SoMFVec2d::copyValue (int to, int from) [protected], [virtual]

This method is what moves values around internally within a multivalue field. It has to be overridden in each field so it automatically takes care of running copy constructors wherever that's necessary. 🧚

Implements SoMField.

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

Returns a pointer to the values array. Point at it, queen. 👑

void SoMFVec2d::initClass (void ) [static]

Internal method that gets called when the library is initialized (from SoDB::init()) to set up the type system. 🛠️

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

Sets num vector array elements from xy, starting at index start. 🌈

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

Sets the vector at idx. 🎯

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

Sets the vector at idx. 🎯

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

Sets this field to contain a single vector with the given element values. One and done. 💖

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

Sets this field to contain a single vector with the given element values. One and done. 💖
