Public Member Functions
	IVtkOCC_ShapeMesher ()
	Main constructor.

virtual	~IVtkOCC_ShapeMesher ()
	Destructor.

Standard_Real	GetDeflection () const
	Returns absolute deflection used by this algorithm. This value is calculated on the basis of the shape's bounding box. Zero might be returned in case if the underlying OCCT shape is empty or invalid. Thus check the returned value before passing it to OCCT meshing algorithms!

Standard_Real	GetDeviationCoeff () const
	Returns relative deviation coefficient used by this algorithm.

Standard_Real	GetDeviationAngle () const
	Returns deviation angle used by this algorithm. This is the maximum allowed angle between the normals to the curve/surface and the normals to polyline/faceted representation.

	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.

Detailed Description

OCC implementation of IMesher interface.

Mesher produces shape data using implementation of IShapeData interface for VTK and then result can be retrieved from this implementation as a vtkPolyData:

Then the resulting vtkPolyData can be used for initialization of VTK pipeline.
