Public Member Functions
	Select3D_SensitiveSphere (const Handle< SelectMgr_EntityOwner > &theOwnerId, const gp_Pnt &theCenter, const Standard_Real theRadius)
	Constructs a sensitive sphere object defined by the owner theOwnerId, the center of the sphere and it's radius.

Standard_Real	Radius () const
	Returns the radius of the sphere.

Public Member Functions inherited from Select3D_SensitiveEntity
const Handle< SelectMgr_EntityOwner > &	OwnerId () const
	Returns pointer to owner of the entity.

virtual void	Set (const Handle< SelectMgr_EntityOwner > &theOwnerId)
	Sets owner of the entity.

Standard_Integer	SensitivityFactor () const
	allows a better sensitivity for a specific entity in selection algorithms useful for small sized entities.

void	SetSensitivityFactor (const Standard_Integer theNewSens)
	Allows to manage sensitivity of a particular sensitive entity.

virtual void	BVH ()
	Builds BVH tree for a sensitive if needed.

virtual void	Clear ()
	Clears up all resources and memory.

virtual Standard_Boolean	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 Handle< Graphic3d_TransformPers > &	TransformPersistence () const
	Return transformation persistence.

virtual void	SetTransformPersistence (const Handle< Graphic3d_TransformPers > &theTrsfPers)
	Set transformation persistence.

virtual void	DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const
	Dumps the content of me into the stream.

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.
