Detailed Description

The SoBBoxModelMatrixElement class keeps track of the current model matrix during a scene graph traversal. It is used by amongst others the SoGetBoundingBoxAction class.

Constructor & Destructor Documentation

~SoBBoxModelMatrixElement()

SoBBoxModelMatrixElement::~SoBBoxModelMatrixElement ( )

protectedvirtual

The destructor.

Member Function Documentation

createInstance()

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.

initClass()

void SoBBoxModelMatrixElement::initClass ( void  )

static

This static method initializes static data for the SoBBoxModelMatrixElement class.

reset()

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.

pushMatrix()

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.

popMatrix()

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.

pushMatrixElt()

SbMatrix SoBBoxModelMatrixElement::pushMatrixElt ( void  )

protectedvirtual

This method is for debug use only.

Reimplemented from SoModelMatrixElement.

popMatrixElt()

void SoBBoxModelMatrixElement::popMatrixElt ( const SbMatrix &  m )

protectedvirtual

This method is for debug use only.

Reimplemented from SoModelMatrixElement.
