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]¶
