Public Member Functions
	Select3D_SensitiveFace (const occ::handle< SelectMgr_EntityOwner > &theOwnerId, const NCollection_Array1< gp_Pnt > &thePoints, const Select3D_TypeOfSensitivity theType)
	Constructs a sensitive face object defined by the owner theOwnerId, the array of points thePoints, and the sensitivity type theType. The array of points is the outer polygon of the geometric face.
	Select3D_SensitiveFace (const occ::handle< SelectMgr_EntityOwner > &theOwnerId, const occ::handle< NCollection_HArray1< gp_Pnt > > &thePoints, const Select3D_TypeOfSensitivity theType)
	Constructs a sensitive face object defined by the owner theOwnerId, the array of points thePoints, and the sensitivity type theType. The array of points is the outer polygon of the geometric face.
occ::handle< NCollection_HArray1< gp_Pnt > >	GetPoints () const
	Returns 3d coordinates of vertices of the face.
void	GetPoints (occ::handle< NCollection_HArray1< gp_Pnt > > &theHArrayOfPnt)
	Initializes the given array theHArrayOfPnt by 3d coordinates of vertices of the face.
bool	Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override
	Checks whether the face overlaps current selecting volume.
occ::handle< Select3D_SensitiveEntity >	GetConnected () override
	Originally this method intended to return sensitive entity with new location aLocation, but currently sensitive entities do not hold a location, instead HasLocation() and Location() methods call corresponding entity owner's methods. Thus all entities returned by GetConnected() share the same location propagated from corresponding selectable object. You must redefine this function for any type of sensitive entity which can accept another connected sensitive entity.
Select3D_BndBox3d	BoundingBox () override
	Returns bounding box of the face. If location transformation is set, it will be applied.
gp_Pnt	CenterOfGeometry () const override
	Returns center of the face. If location transformation is set, it will be applied.
void	BVH () override
	Builds BVH tree for the face.
bool	ToBuildBVH () const override
	Returns TRUE if BVH tree is in invalidated state.
int	NbSubElements () const override
	Returns the amount of sub-entities (points or planar convex polygons).
void	DumpJson (Standard_OStream &theOStream, int theDepth=-1) const override
	Dumps the content of me into the stream.

void	SetSensitivityFactor (const int theNewSens)
	Allows to manage sensitivity of a particular sensitive entity.
virtual void	Clear ()
	Clears up all resources and memory.
virtual bool	HasInitLocation () const
	Returns true if the shape corresponding to the entity has init location.
virtual gp_GTrsf	InvInitLocation () const
	Returns inversed location transformation matrix if the shape corresponding to this entity has init location set. Otherwise, returns identity matrix.
const occ::handle< Graphic3d_TransformPers > &	TransformPersistence () const
	Return transformation persistence.
virtual void	SetTransformPersistence (const occ::handle< Graphic3d_TransformPers > &theTrsfPers)
	Set transformation persistence.

	Return flipper metadata describing the runtime flip of the owning group, or null.
virtual void	SetFlippingOptions (const bool theIsEnabled, const gp_Ax2 &theRefPlane)
	Set flipping options. When enabled, creates a Graphic3d_Flipper for theRefPlane; otherwise clears the flipper.
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.

Additional Inherited Members
typedef void	base_type
	Returns a type descriptor about this object.
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.
