👑 Detailed Description 👑

okay bestie, the whole point of SoComputeBoundingBox? It calculates a bounding box. ✨

And here's the tea: this engine is simply a wrapper around the SoGetBoundingBoxAction. It's the convenient little way of having automatic updating of some data in the scene graph that depends on the bounding box of some other part of the scene. Basically it does the watching for you so you don't have to. 🫶

🧚 Constructor & Destructor Documentation 🧚

🌸 `SoComputeBoundingBox::SoComputeBoundingBox (void )`

Default constructor. It sets up the internal SoGetBoundingBoxAction instance. ✨

References boxCenter, max, min, node, objectCenter, path, and SoComputeBoundingBox().

Referenced by getFieldData(), and SoComputeBoundingBox().

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

Destructor. It deallocates the SoGetBoundingBoxAction instance. bye boo 👋

💅 Member Function Documentation 💅

⭐ `SoType SoComputeBoundingBox::getTypeId (void ) const [virtual]`

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

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::getFieldData (void ) const [virtual]`

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

Reimplemented from SoFieldContainer.

References SoComputeBoundingBox().

⭐ `const SoEngineOutputData * SoComputeBoundingBox::getOutputData (void ) const [virtual]`

ngl bestie, this API member is considered internal to the library, since it is not likely to be of interest to the application programmer. so like… noted. 🙈

Implements SoEngine.

⭐ `void SoComputeBoundingBox::setViewportRegion (const SbViewportRegion & vpr)`

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

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

⭐ `const SbViewportRegion & SoComputeBoundingBox::getViewportRegion (void ) const`

Returns the 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.
