SoMFVec4f(3)

📦 version 3.1.3, in fedora 43, fedora 44

💖 NAME 💖

SoMFVec4f — the class that's literally a container for SbVec4f vectors. bestie it holds vectors. four elements each. slay.

✨ SYNOPSIS ✨

okay so first you gotta pull it in:

#include <Inventor/fields/SoMFVec4f.h>

and it inherits from SoMField. that's the family tree, no cap.

💖 DESCRIPTION 💖

okay so real talk: SoMFVec4f is a container for SbVec4f vectors. that's the whole gig and it's iconic.

this field is the one you reach for when nodes, engines or other field containers need to store an array of vectors with four elements. four. every time. it's giving consistent.

this field also supports application data sharing through a setValuesPointer() method. wanna know how to actually use that? the SoMField documentation has the tea, go read it bestie.

✨ Member Function Documentation ✨

SoType SoMFVec4f::getTypeId (void ) const [virtual]

returns the type identification instance which uniquely identifies the Coin field class the object belongs to. it's the ID card. the birth certificate. the vibe check for classes.

See also

  • getClassTypeId(), SoType

implements SoField.

void SoMFVec4f::copyFrom (const SoField & f) [virtual]

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

implements SoField.

SbBool SoMFVec4f::isSame (const SoField & f) const [virtual]

check for equal type and value(s). basically asking "are we twins or not".

implements SoField.

void SoMFVec4f::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. so like... not for you bestie, but it's here.

implements SoMField.

void SoMFVec4f::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 contructors where necessary. (yes, "contructors" — we keep the typo, it's part of the lore 💀)

implements SoMField.

const SbVec4f * SoMFVec4f::getValues (const int start) const [inline]

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

void SoMFVec4f::setValues (int start, int numarg, const float xyzw[][4])

set num vector array elements from xyzw, starting at index start. wait, we said num — the parameter is literally called numarg, keep it exact bestie.

void SoMFVec4f::set1Value (int idx, float x, float y, float z, float w)

set the vector at idx. four floats in, one vector out. iconic.

void SoMFVec4f::set1Value (int idx, const float xyzw[4])

set the vector at idx. same energy, array flavoured.

void SoMFVec4f::setValue (float x, float y, float z, float w)

set this field to contain a single vector with the given element values. one vector. just one. main character energy.

void SoMFVec4f::setValue (const float xyzw[4])

set this field to contain a single vector with the given element values. again, but you're handing it an array this time. same slay.
