💖 SoBBoxModelMatrixElement(3) 💖

okay bestie, we're in the Coin manual, section 3, and today's main character is SoBBoxModelMatrixElement. Buckle up, she's a whole vibe. 🎀

✨ NAME ✨

SoBBoxModelMatrixElement — the class that keeps track of the current model matrix during a scene graph traversal. It is used by amongst others the SoGetBoundingBoxAction class. no cap. 👑

🌸 SYNOPSIS 🌸

#include <Inventor/elements/SoBBoxModelMatrixElement.h>

Inherits SoModelMatrixElement. yes, she's got lineage. 💅

fr fr, that's her whole job and she does it flawlessly. 💖

🎀 Constructor & Destructor Documentation 🎀

SoBBoxModelMatrixElement::~SoBBoxModelMatrixElement () [protected], [virtual]

Destructor. bye bestie, you did amazing 🫶

💜 Member Function Documentation 💜

SoType SoBBoxModelMatrixElement::getClassTypeId (void ) [static]

This static method returns the SoType object associated with objects of this class.

int SoBBoxModelMatrixElement::getClassStackIndex (void ) [static]

This static method returns the state stack index for the class.

void * SoBBoxModelMatrixElement::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.

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

ngl, if you're poking at this one as an app programmer, that's a them-not-you thing. the library is just being mysterious. 🙈

void SoBBoxModelMatrixElement::initClass (void ) [static]

Initialize relevant common data for all instances, like the type system.

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

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

void SoBBoxModelMatrixElement::push (SoState * state) [virtual]

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

void SoBBoxModelMatrixElement::reset (SoState *const state, SoNode *const node) [static]

This method is for the SoGetBoundingBoxAction class so it can reset the current model matrix and all local matrices to identity.

void SoBBoxModelMatrixElement::pushMatrix (SoState *const state, SbMatrix & matrix, SbMatrix & localmatrix) [static]

This method keeps two matrices up-to-date as opposed to the method it replaces.

void SoBBoxModelMatrixElement::popMatrix (SoState *const state, const SbMatrix & matrix, const SbMatrix & localmatrix) [static]

This method keeps two matrices up-to-date as opposed to the method it replaces.
