Constructor & Destructor Documentation

~SoViewingMatrixElement()

SoViewingMatrixElement::~SoViewingMatrixElement ( void )

protectedvirtual

Destructor.

Member Function Documentation

createInstance()

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.

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

getClassStackIndex()

int SoViewingMatrixElement::getClassStackIndex ( void )

static

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

getClassTypeId()

SoType SoViewingMatrixElement::getClassTypeId ( void )

static

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

init()

void SoViewingMatrixElement::init ( SoState * state )

virtual

Initializes the element to its default value. The default value is the identity matrix.

Reimplemented from SoReplacedElement.

Reimplemented in SoGLViewingMatrixElement.

initClass()

void SoViewingMatrixElement::initClass ( void )

static

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

setElt()

void SoViewingMatrixElement::setElt ( const SbMatrix & matrix )

protectedvirtual

FIXME: write doc.

Reimplemented in SoGLViewingMatrixElement.
