Public Member Functions
	BVH_SweepPlaneBuilder (const Standard_Integer theLeafNodeSize=BVH_Constants_LeafNodeSizeDefault, const Standard_Integer theMaxTreeDepth=BVH_Constants_MaxTreeDepth, const Standard_Integer theNumOfThreads=1)
	Creates sweep plane SAH BVH builder.

virtual	~BVH_SweepPlaneBuilder ()
	Releases resources of sweep plane SAH BVH builder.

Public Member Functions inherited from BVH_QueueBuilder< T, N >
	BVH_QueueBuilder (const Standard_Integer theLeafNodeSize, const Standard_Integer theMaxTreeDepth, const Standard_Integer theNumOfThreads=1)
	Creates new BVH queue based builder.

virtual	~BVH_QueueBuilder ()
	Releases resources of BVH queue based builder.

virtual void	Build (BVH_Set< T, N > theSet, BVH_Tree< T, N > theBVH, const BVH_Box< T, N > &theBox) const override
	Builds BVH using specific algorithm.

Public Member Functions inherited from BVH_BuilderTransient
Standard_Integer	MaxTreeDepth () const
	Returns the maximum depth of constructed BVH.

Standard_Integer	LeafNodeSize () const
	Returns the maximum number of sub-elements in the leaf.

Standard_Boolean	IsParallel () const
	Returns parallel flag.

void	SetParallel (const Standard_Boolean isParallel)
	Set parallel flag controlling possibility of parallel execution.

Public Member Functions inherited from Standard_Transient
	Standard_Transient ()
	Empty constructor.

	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.

Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.

virtual	~Standard_Transient ()
	Destructor must be virtual.

virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.

Standard_Boolean	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.

Standard_Boolean	IsInstance (const Standard_CString theTypeName) const
	Returns a true value if this is an instance of TypeName.

Standard_Boolean	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Boolean	IsKind (const Standard_CString theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.

Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.

Standard_Integer	GetRefCount () const noexcept
	Get the reference counter of this object.

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object.

Standard_Integer	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value.

virtual void	Delete () const
	Memory deallocator for transient classes.
