🎀 Constructor & Destructor Documentation 🎀

SoViewingMatrixElement::~SoViewingMatrixElement (void ) [protected], [virtual]

Destructor. it does the goodbye thing 🫶

💖 Member Function Documentation 💖

SoType SoViewingMatrixElement::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class. iykyk, it's the class's little ID card 🎀

int SoViewingMatrixElement::getClassStackIndex (void ) [static]

This static method returns the state stack index for the class. literally the address of where it lives on the stack, periodt. ✨

void * SoViewingMatrixElement::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, not your problem bestie 🙈

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

void SoViewingMatrixElement::initClass (void ) [static]

Initialize relevant common data for all instances, like the type system. one big group-chat setup for everybody 💫

void SoViewingMatrixElement::init (SoState * state) [virtual]

Initializes the element to its default value. The default value is the identity matrix. the classic, the default, the main character 👑

Reimplemented from SoReplacedElement.

Reimplemented in SoGLViewingMatrixElement.

void SoViewingMatrixElement::setElt (const SbMatrix & matrix) [protected], [virtual]

FIXME: write doc. yeah. still that. 😭

Reimplemented in SoGLViewingMatrixElement.
