Public Member Functions | |
| virtual void | init (SoState *state) |
| Initializes element. | |
| virtual void | push (SoState *state) |
| Overrides push() method to copy values from next instance in the stack. | |
Static Public Member Functions | |
| 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; TransformSeparator::getBoundingBox uses these methods to correctly keep both matrices up-to-date. | |
| static void | popMatrix (SoState *state, const SbMatrix &matrix, const SbMatrix &localmatrix) |
| static void | initClass () |
| Initializes the SoBBoxModelMatrixElement class. | |
Protected Member Functions | |
| virtual void | makeEltIdentity () |
| These all override the methods on SoModelMatrixElement to also set the SoLocalBBoxMatrixElement. | |
| virtual void | setElt (const SbMatrix &matrix) |
| Sets the matrix in an instance to given matrix. | |
| virtual void | multElt (const SbMatrix &matrix) |
| Multiplies into the matrix in an instance. | |

| Each of these performs the appropriate operation on the matrix in an instance. | |

Detailed Description
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.
