Public Member Functions

 Select3D_SensitivePoint (const Handle< SelectMgr_EntityOwner > &theOwnerId, const gp_Pnt &thePoint)
 Constructs a sensitive point object defined by the owner OwnerId and the point Point.
 
virtual Standard_Integer NbSubElements () const override
 Returns the amount of sub-entities in sensitive.
 
virtual Handle< Select3D_SensitiveEntityGetConnected () 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.
 
virtual Standard_Boolean Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override
 Checks whether the point overlaps current selecting volume.
 
const gp_PntPoint () const
 Returns the point used at the time of construction.
 
virtual gp_Pnt CenterOfGeometry () const override
 Returns center of point. If location transformation is set, it will be applied.
 
virtual Select3D_BndBox3d BoundingBox () override
 Returns bounding box of the point. If location transformation is set, it will be applied.
 
virtual Standard_Boolean ToBuildBVH () const override
 Returns TRUE if BVH tree is in invalidated state.
 
virtual void DumpJson (Standard_OStream &theOStream, Standard_Integer theDepth=-1) const override
 Dumps the content of me into the stream.
 
- 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.
 
- Public Member Functions inherited from Standard_Transient
 Standard_Transient ()
 Empty constructor.
 
 Standard_Transient (const Standard_Transient &)
 Copy constructor – does nothing.
 
Standard_Transientoperator= (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_TransientThis () 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.
