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 *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.

Reimplemented from SoModelMatrixElement.

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

Reimplemented from SoModelMatrixElement.
