NAME

       SoBBoxModelMatrixElement -

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

       The destructor.

Member Function Documentation

   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 *conststate, SoNode *constnode) [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 *conststate, SbMatrix &matrix, SbMatrix
       &localmatrix) [static]
       This method keeps two matrices up-to-date as opposed to the method it replaces.

   void SoBBoxModelMatrixElement::popMatrix (SoState *conststate, 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.

       Reimplemented from SoModelMatrixElement.

   void SoBBoxModelMatrixElement::popMatrixElt (const SbMatrix &m) [protected],  [virtual]
       This method is for debug use only.

       Reimplemented from SoModelMatrixElement.
