Constructor & Destructor Documentation
   SoViewingMatrixElement::~SoViewingMatrixElement (void) [protected],
       [virtual]
       Destructor.

Member Function Documentation
   SoType SoViewingMatrixElement::getClassTypeId (void) [static]
       This static method returns the SoType object associated with objects of
       this class.


   int SoViewingMatrixElement::getClassStackIndex (void) [static]
       This static method returns the state stack index for the class.


   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.


   void SoViewingMatrixElement::initClass (void) [static]
       Initialize relevant common data for all instances, like the type
       system.

   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.

   void SoViewingMatrixElement::setElt (const SbMatrix & matrix) [protected],
       [virtual]
       FIXME: write doc.

       Reimplemented in SoGLViewingMatrixElement.
