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 ( ) [protected, virtual]

The destructor.

SoType SoBBoxModelMatrixElement::getClassTypeId ( void ) [static]

This static method returns the class type.

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.

void SoBBoxModelMatrixElement::initClass ( void ) [static]

This static method initializes static data for the SoBBoxModelMatrixElement class.

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.

SbMatrix SoBBoxModelMatrixElement::pushMatrixElt ( void ) [protected, virtual]

This method is for debug use only.

void SoBBoxModelMatrixElement::popMatrixElt ( const SbMatrix & m ) [protected, virtual]

This method is for debug use only.
