Detailed Description

The SoComputeBoundingBox class is used to calculate a bounding box.

This engine is simply a wrapper around the SoGetBoundingBoxAction, for a convenient way of having automatic updating of some data in the scene graph which is dependent on the bounding box of some other part of the scene.


Constructor & Destructor Documentation

SoComputeBoundingBox::SoComputeBoundingBox ( void  )

Default constructor. Sets up the internal SoGetBoundingBoxAction instance.

References boxCenter, max, min, node, objectCenter, and path.

SoComputeBoundingBox::~SoComputeBoundingBox ( )
protectedvirtual

Destructor. Deallocate the SoGetBoundingBoxAction instance.


Member Function Documentation

SoType SoComputeBoundingBox::getClassTypeId ( void  )
static

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

Reimplemented from SoEngine.

SoType SoComputeBoundingBox::getTypeId ( void  ) const
virtual

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.

const SoFieldData ** SoComputeBoundingBox::getInputDataPtr ( void  )
staticprotected

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

Reimplemented from SoEngine.

const SoEngineOutputData ** SoComputeBoundingBox::getOutputDataPtr ( void  )
staticprotected

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

Reimplemented from SoEngine.

const SoFieldData * SoComputeBoundingBox::getFieldData ( void  ) const
virtual

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

Reimplemented from SoFieldContainer.

const SoEngineOutputData * SoComputeBoundingBox::getOutputData ( void  ) const
virtual

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

Implements SoEngine.

void SoComputeBoundingBox::initClass ( void  )
static

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

Reimplemented from SoEngine.

void SoComputeBoundingBox::setViewportRegion ( const SbViewportRegion vpr)

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.

References SoGetBoundingBoxAction::setViewportRegion().

const SbViewportRegion & SoComputeBoundingBox::getViewportRegion ( void  ) const

Returns viewport region used by the internal SoGetBoundingBoxAction instance.

References SoGetBoundingBoxAction::getViewportRegion().


Member Data Documentation

SoSFNode SoComputeBoundingBox::node

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.

Referenced by SoComputeBoundingBox().

SoSFPath SoComputeBoundingBox::path

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

Referenced by SoComputeBoundingBox().

SoEngineOutput SoComputeBoundingBox::min

(SoSFVec3f) Corner coordinates of the bounding box.

Referenced by SoComputeBoundingBox().

SoEngineOutput SoComputeBoundingBox::max

(SoSFVec3f) Corner coordinates of the bounding box.

Referenced by SoComputeBoundingBox().

SoEngineOutput SoComputeBoundingBox::boxCenter

(SoSFVec3f) Geometric center point of the bounding box.

Referenced by SoComputeBoundingBox().

SoEngineOutput SoComputeBoundingBox::objectCenter

(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.
