Public Member Functions

 MeshVS_SensitiveMesh (const occ::handle< SelectMgr_EntityOwner > &theOwner, const int theMode=0)
 
int GetMode () const
 
occ::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.
 
bool Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override
 Checks whether sensitive overlaps current selecting volume.
 
int NbSubElements () const override
 Returns the amount of mesh nodes.
 
Select3D_BndBox3d BoundingBox () override
 Returns bounding box of mesh.
 
gp_Pnt CenterOfGeometry () const override
 Returns center of mesh.
 
- Public Member Functions inherited from Select3D_SensitiveEntity
const occ::handle< SelectMgr_EntityOwner > & OwnerId () const
 Returns pointer to owner of the entity.
 
virtual void Set (const occ::handle< SelectMgr_EntityOwner > &theOwnerId)
 Sets owner of the entity.
 
int SensitivityFactor () const
 allows a better sensitivity for a specific entity in selection algorithms useful for small sized entities.
 
void SetSensitivityFactor (const int theNewSens)
 Allows to manage sensitivity of a particular sensitive entity.
 
virtual void BVH ()
 Builds BVH tree for a sensitive if needed.
 
virtual bool ToBuildBVH () const
 Returns TRUE if BVH tree is in invalidated state.
 
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.
 
const occ::handle< Graphic3d_Flipper > & Flipper () const
 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.
 
virtual void DumpJson (Standard_OStream &theOStream, int 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_Transientoperator= (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_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.
 
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.
