Default constructor. Sets up the internal SoGetBoundingBoxAction instance.

Destructor. Deallocate the SoGetBoundingBoxAction instance.

This static method returns the SoType object associated with objects of this class.

Reimplemented from SoEngine.

Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time type checking and 'downward' casting.

Usage example:

  void foo(SoNode * node)
  {
    if (node->getTypeId() == SoFile::getClassTypeId()) {
      SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
    }
    else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
      SoGroup * group = (SoGroup *)node;  // safe downward cast, knows the type
    }
  }

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups.

Implements SoBase.

Returns the SoFieldData class which holds information about inputs in this engine.

Reimplemented from SoEngine.

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

Reimplemented from SoEngine.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoEngine.

Set viewport region for the SoGetBoundingBoxAction instance we're using for calculating bounding boxes.

The default setting is to use an SbViewportRegion with only default values.

Returns viewport region used by the internal SoGetBoundingBoxAction instance.

If this input field is set and SoComputeBoundingBox::path is NULL, the resultant bounding box will be the box encompassing the scene graph rooted at this node pointer.

If this input field is not NULL, the bounding box values of the given path will be set on the outputs.

(SoSFVec3f) Corner coordinates of the bounding box.

(SoSFVec3f) Corner coordinates of the bounding box.

(SoSFVec3f) Geometric center point of the bounding box.

(SoSFVec3f) Object center point for the bounding box. See SoGetBoundingBoxAction::getCenter() for an explanation for how this can differ from the geometric center point of the bounding box.
