This class Provides a polygon in 3D space. It is generally an approximate representation of a curve. A Polygon3D is defined by a table of nodes. Each node is a 3D point. If the polygon is closed, the point of closure is repeated at the end of the table of nodes. If the polygon is an approximate representation of a curve, you can associate with each of its nodes the value of the parameter of the corresponding point on the curve.

|
| | Poly_Polygon3D (const int theNbNodes, const bool theHasParams) |
| | Constructs a 3D polygon with specific number of nodes.
|
| |
| | Poly_Polygon3D (const NCollection_Array1< gp_Pnt > &Nodes) |
| | Constructs a 3D polygon defined by the table of points, Nodes.
|
| |
| | Poly_Polygon3D (const NCollection_Array1< gp_Pnt > &Nodes, const NCollection_Array1< double > &Parameters) |
| | Constructs a 3D polygon defined by the table of points, Nodes, and the parallel table of parameters, Parameters, where each value of the table Parameters is the parameter of the corresponding point on the curve approximated by the constructed polygon. Warning Both the Nodes and Parameters tables must have the same bounds. This property is not checked at construction time.
|
| |
| virtual occ::handle< Poly_Polygon3D > | Copy () const |
| | Creates a copy of current polygon.
|
| |
| double | Deflection () const |
| | Returns the deflection of this polygon.
|
| |
| void | Deflection (const double theDefl) |
| | Sets the deflection of this polygon. See more on deflection in Poly_Polygon2D.
|
| |
| int | NbNodes () const |
| | Returns the number of nodes in this polygon. Note: If the polygon is closed, the point of closure is repeated at the end of its table of nodes. Thus, on a closed triangle the function NbNodes returns 4.
|
| |
| const NCollection_Array1< gp_Pnt > & | Nodes () const |
| | Returns the table of nodes for this polygon.
|
| |
| NCollection_Array1< gp_Pnt > & | ChangeNodes () |
| | Returns the table of nodes for this polygon.
|
| |
| bool | HasParameters () const |
| | Returns the table of the parameters associated with each node in this polygon. HasParameters function checks if parameters are associated with the nodes of this polygon.
|
| |
| const NCollection_Array1< double > & | Parameters () const |
| | Returns true if parameters are associated with the nodes in this polygon.
|
| |
| NCollection_Array1< double > & | ChangeParameters () const |
| | Returns the table of the parameters associated with each node in this polygon. ChangeParameters function returns the array as shared. Therefore if the table is selected by reference you can, by simply modifying it, directly modify the data structure of this polygon.
|
| |
| 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.
