Public Member Functions

 IVtkOCC_ShapeMesher ()
 Main constructor.
 
 ~IVtkOCC_ShapeMesher () override
 Destructor.
 
double 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!
 
double GetDeviationCoeff () const
 Returns relative deviation coefficient used by this algorithm.
 
double 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.

void Build (const IVtk_IShape::Handle &theShape, const IVtk_IShapeData::Handle &theData)
 Main entry point for building shape representation.

- 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.

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.
