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

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.

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

◆ getClassStackIndex()

int SoBBoxModelMatrixElement::getClassStackIndex ( void )

static

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

◆ getClassTypeId()

SoType SoBBoxModelMatrixElement::getClassTypeId ( void )

static

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

◆ init()

void SoBBoxModelMatrixElement::init ( SoState * state )

overridevirtual

FIXME: write doc.

Reimplemented from SoAccumulatedElement.

◆ initClass()

void SoBBoxModelMatrixElement::initClass ( void )

static

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

◆ makeEltIdentity()

void SoBBoxModelMatrixElement::makeEltIdentity ( void )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

◆ multElt()

void SoBBoxModelMatrixElement::multElt ( const SbMatrix & matrix )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

◆ 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.

◆ popMatrixElt()

void SoBBoxModelMatrixElement::popMatrixElt ( const SbMatrix & m )

overrideprotectedvirtual

This method is for debug use only.

Reimplemented from SoModelMatrixElement.

◆ push()

void SoBBoxModelMatrixElement::push ( SoState * state )

overridevirtual

FIXME: write doc.

Reimplemented from SoAccumulatedElement.

◆ 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.

◆ pushMatrixElt()

SbMatrix SoBBoxModelMatrixElement::pushMatrixElt ( void )

overrideprotectedvirtual

This method is for debug use only.

Reimplemented from SoModelMatrixElement.

◆ 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.

◆ rotateEltBy()

void SoBBoxModelMatrixElement::rotateEltBy ( const SbRotation & translation )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

◆ scaleEltBy()

void SoBBoxModelMatrixElement::scaleEltBy ( const SbVec3f & scaleFactor )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

◆ setElt()

void SoBBoxModelMatrixElement::setElt ( const SbMatrix & matrix )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.

◆ translateEltBy()

void SoBBoxModelMatrixElement::translateEltBy ( const SbVec3f & translation )

overrideprotectedvirtual

FIXME: write doc.

Reimplemented from SoModelMatrixElement.
