Public Member Functions inherited from BVH_PrimitiveSet< T, N >
	BVH_PrimitiveSet ()
	Creates set of abstract primitives.

	Creates set of abstract primitives.

	~BVH_PrimitiveSet () override
	Releases resources of set of abstract primitives.

	Returns AABB of primitive set.

virtual const opencascade::handle< BVH_Tree< T, N > > &	BVH ()
	Returns BVH tree (and builds it if necessary).

virtual const opencascade::handle< BVH_Builder< T, N > > &	Builder () const
	Returns the method (builder) used to construct BVH.

virtual void	SetBuilder (const opencascade::handle< BVH_Builder< T, N > > &theBuilder)
	Sets the method (builder) used to construct BVH.

Public Member Functions inherited from BVH_Object< T, N >
	BVH_Object ()=default
	Creates new abstract geometric object.

	~BVH_Object () override=default
	Releases resources of geometric object.

Public Member Functions inherited from BVH_ObjectTransient
virtual const occ::handle< BVH_Properties > &	Properties () const
	Returns properties of the geometric object.

virtual void	SetProperties (const occ::handle< BVH_Properties > &theProperties)
	Sets properties of the geometric object.

virtual bool	IsDirty () const
	Returns TRUE if object state should be updated.

virtual void	MarkDirty ()
	Marks object state as outdated (needs BVH rebuilding).

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 ()=default
	Destructor must be virtual.

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

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

bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.

bool	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.

bool	IsKind (const char *const 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.

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

void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.

int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.

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

Public Member Functions inherited from BVH_Set< T, N >
	BVH_Set ()=default
	Creates new abstract set of objects.

virtual	~BVH_Set ()=default
	Releases resources of set of objects.

Data Fields
BVH::ArrayType< T, N >::Type	Vertices
	Array of vertex coordinates.

BVH_Array4i	Elements
	Array of indices of triangle vertices.
