Public Member Functions
	SoBoundingBoxCache (SoState *state)
	Constructor and destructor.
	~SoBoundingBoxCache ()
void	set (const SbXfBox3f &boundingBox, bool centerSet, const SbVec3f &centerPoint)
	Stores a bounding box and center point in the cache.
const SbXfBox3f &	getBox () const
const SbBox3f &	getProjectedBox () const
bool	isCenterSet () const
	Returns TRUE if the center is valid.
const SbVec3f &	getCenter () const
	Returns the center (in object space)
bool	hasLinesOrPoints () const
	Returns the hasLinesOrPoints flag.
Public Member Functions inherited from SoCache
	SoCache (SoState *state)
	Constructor.
void	ref ()
	Reference/unreference.
void	unref (SoState *state=NULL)
void	addElement (const SoElement *elt)
	Adds an element to elements-used list if not already there.
virtual void	addCacheDependency (const SoState *state, SoCache *cache)
	Adds a dependency of this instance on another cache instance.
virtual bool	isValid (const SoState *state) const
	Returns TRUE if cache is valid with respect to the given state.
const SoElement *	getInvalidElement (const SoState *state) const
	Assuming isValid() returns FALSE, this will return the first element that is invalid (auto-caching uses this in its heuristic).
void	invalidate ()
	Make this cache invalid.

Static Public Member Functions
static void	setHasLinesOrPoints (SoState *state)
	Sets the hasLinesOrPoints flag to TRUE in all open bounding box caches in the given state.

Additional Inherited Members
Protected Member Functions inherited from SoCache
virtual void	destroy (SoState *state)
	Subclasses can use this to clean up just before they are deleted.
virtual	~SoCache ()
	Destructor.

Detailed Description

A bounding box cache stores a bounding box and center point. It also stores a flag indicating whether the box contains any line or point objects, meaning that intersection tests with the box should use a little extra leeway.
