Public Member Functions | |
| MeshVS_SensitivePolyhedron (const occ::handle< SelectMgr_EntityOwner > &theOwner, const NCollection_Array1< gp_Pnt > &theNodes, const occ::handle< NCollection_HArray1< NCollection_Sequence< int > > > &theTopo) | |
| 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. | |
| bool | Matches (SelectBasics_SelectingVolumeManager &theMgr, SelectBasics_PickResult &thePickResult) override |
| Checks whether sensitive overlaps current selecting volume. Stores minimum depth, distance to center of geometry and closest point detected into thePickResult. | |
| int | NbSubElements () const override |
| Returns the amount of nodes of polyhedron. | |
| Select3D_BndBox3d | BoundingBox () override |
| Returns bounding box of a sensitive with transformation applied. | |
| gp_Pnt | CenterOfGeometry () const override |
| Returns center of a sensitive with transformation applied. | |
 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_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 | |
| Public Types inherited from Standard_Transient | |

| Static Public Member Functions inherited from Standard_Transient | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
