SoBBoxModelMatrixElement

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.

Member Function Documentation

void SoBBoxModelMatrixElement::initClass (void) [static]This static method initializes static data for the SoBBoxModelMatrixElement class.

Reimplemented from SoModelMatrixElement.

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.
