Inheritance diagram for BVH_Transform< T, N >:

Public Types
typedef BVH::MatrixType< T, N >::Type	BVH_MatNt
	Type of transformation matrix.
typedef void	base_type
	Returns a type descriptor about this object.

Public Member Functions
	BVH_Transform ()=default
	Creates new identity transformation.
	BVH_Transform (const BVH_MatNt &theTransform)
	Creates new transformation with specified matrix.
	~BVH_Transform () override=default
	Releases resources of transformation properties.
const BVH_MatNt &	Transform () const
	Returns transformation matrix.
void	SetTransform (const BVH_MatNt &theTransform)
	Sets new transformation matrix.
const BVH_MatNt &	Inversed () const
	Returns inversed transformation matrix.
BVH_Box< T, N >	Apply (const BVH_Box< T, N > &theBox) const
	Applies transformation matrix to bounding box.
Public Member Functions inherited from BVH_Properties
	~BVH_Properties () override=0
	Releases resources of object properties.
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.

Protected Attributes
BVH_MatNt	myTransform
	Transformation matrix.
BVH_MatNt	myTransformInversed
	Inversed transformation matrix.

Additional Inherited Members
static constexpr const char *	get_type_name ()
	Returns a type descriptor about this object.
static const opencascade::handle< Standard_Type > &	get_type_descriptor ()
	Returns type descriptor of Standard_Transient class.
