SoMFVec4d(3)

💖 SoMFVec4d — NAME 💖

okay so bestie, welcome to the SoMFVec4d(3) page from the Coin library 💅 this is the section-3 manual entry, and it's all about one lil class:

SoMFVec4d — it's a container for SbVec4d vectors. that's it, that's the whole vibe. a multi-field that holds a whole array of four-element double vectors. slay ✨

🌸 DETAILED DESCRIPTION 🌸

okay so, SoMFVec4d is a container for SbVec4d vectors, periodt. 💅

this field is what you reach for when nodes, engines, or other field containers need to store an array of vectors with four elements. like, a whole squad of SbVec4ds, all chilling in one field. iconic.

this field supports application data sharing through a setValuesPointer() method. bestie if you wanna know how to actually use that, go read the SoMField documentation, it's all there. 📚

See also: SbVec4d, SoSFVec4d

⚠️ real talk: 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 old SGI code, don't come for me. 😭

Since: Coin 2.5 🎉

🎀 MEMBER FUNCTION DOCUMENTATION 🎀

void * SoMFVec4d::createInstance (void ) [static]

this API member is considered internal to the library, as it is not likely to be of interest to the application programmer. so like, it's giving backstage pass energy — not for the general public. 🙈

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

SoType SoMFVec4d::getClassTypeId (void ) [static]

this static method returns the SoType object associated with objects of this class. it's how the type system knows who you are at runtime. slay.

SoType SoMFVec4d::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.

Implements SoField.

void SoMFVec4d::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, no matching, okay bestie? ✋

Implements SoField.

SbBool SoMFVec4d::isSame (const SoField & f) const [virtual]

check for equal type and value(s). basically a vibe check for fields. 💅

Implements SoField.

void SoMFVec4d::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 SoMFVec4d::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. so like, don't skip it when you're subclassing, fr fr.

Implements SoMField.

const SbVec4d * SoMFVec4d::getValues (const int start) const [inline]

returns a pointer to the values array. 🫶 just a lil pointer, no cap.

void SoMFVec4d::initClass (void ) [static]

internal method called upon initialization of the library (from SoDB::init()) to set up the type system. it's the behind-the-scenes main character. ✨

void SoMFVec4d::setValues (int start, int numarg, const double xyzw[][4])

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

void SoMFVec4d::set1Value (int idx, double x, double y, double z, double w)

set the vector at idx. one vector, four doubles, zero drama.

void SoMFVec4d::set1Value (int idx, const double xyzw[4])

set the vector at idx.

void SoMFVec4d::setValue (double x, double y, double z, double w)

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

void SoMFVec4d::setValue (const double xyzw[4])

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