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.

SoComputeBoundingBox::~SoComputeBoundingBox (  )  [protected, virtual]

Destructor. Deallocate the SoGetBoundingBoxAction instance.

Member Function Documentation

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.

const SbViewportRegion & SoComputeBoundingBox::getViewportRegion (  void )  const

Returns viewport region used by the internal SoGetBoundingBoxAction instance.

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.

SoSFPath SoComputeBoundingBox::path

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

SoEngineOutput SoComputeBoundingBox::min

(SoSFVec3f) Corner coordinates of the bounding box.

SoEngineOutput SoComputeBoundingBox::max

(SoSFVec3f) Corner coordinates of the bounding box.

SoEngineOutput SoComputeBoundingBox::boxCenter

(SoSFVec3f) Geometric center point of the bounding box.

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.
