Returns type identifier for element instance. | |

SbBool | isOfType (const SoType &type) const |
Returns TRUE if this object is of the type specified in type or is derived from that type. | |

SbBool | isOfType () const |
Returns TRUE if this object is of the type of class TypedObjectClass or is derived from that class. | |
Static Public Member Functions | |
static SoType | getClassTypeId () |
Returns the type identifier for this class. | |
static int | getClassStackIndex () |
Returns the stack id for this element. | |
static void | reset (SoState *state, SoNode *node) |
Allows the SoGetBoundingBoxAction to reset the current model matrix to identity and all currently-open local matrices to identity. | |
static void | pushMatrix (SoState *state, SbMatrix &matrix, SbMatrix &localmatrix) |
Because two model matrices are kept track of during the getBoundingBoxAction (the local model matrix, used by separators to calculate their bbox caches, and the real model matrix), replacement routines for pushMatrix/popMatrix must be given; SoTransformSeparator::getBoundingBox uses these methods to correctly keep both matrices up-to-date. | |
static void | popMatrix (SoState *state, const SbMatrix &matrix, const SbMatrix &localmatrix) |
See description for pushMatrix(). | |

Stores the current model matrix for use with the SoGetBoundingBoxAction.
This element stores the current model matrix for use with the SoGetBoundingBoxAction. Overrides the virtual methods on SoModelMatrixElement to also set the current SoLocalBBoxMatrixElement.
This class relies on SoModelMatrixElement to store the matrix in the instance, and inherits most of its methods from it.
