The destructor.

Member Function Documentation

void * SoBBoxModelMatrixElement::createInstance (void)\fC [static]\fP

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)\fC [static]\fP

This static method initializes static data for the SoBBoxModelMatrixElement class.

void SoBBoxModelMatrixElement::reset (\fBSoState\fP conststate, \fBSoNode\fP constnode)\fC [static]\fP

This method is for the SoGetBoundingBoxAction class so it can reset the current model matrix and all local matrices to identity.

void SoBBoxModelMatrixElement::pushMatrix (\fBSoState\fP *conststate, \fBSbMatrix\fP &matrix, \fBSbMatrix\fP &localmatrix)\fC [static]\fP

This method keeps two matrices up-to-date as opposed to the method it replaces.

void SoBBoxModelMatrixElement::popMatrix (\fBSoState\fP *conststate, const \fBSbMatrix\fP &matrix, const \fBSbMatrix\fP &localmatrix)\fC [static]\fP
