MbMeshProcessor Class – Shell Creation
======================================
.. _MbMeshProcessor_class–shell_creation_:


.. kernel version: 


The :blue:`MbMeshProcessor` class is intended for creating a shell based on a polygonal mesh with user-defined settings. The class provides advanced capabilities for controlling segmentation and surface recognition processes.


.. code-block:: cpp

   class MbMeshProcessor {

   public:
       // Create a processor instance by a collection of elements.
       MbMeshProcessor * Create( const MbCollection & collection );

       // Destructor
       ~MbMeshProcessor();

       // Recognition tolerance control
       void   SetRelativeTolerance( double tolerance );
       void   SetTolerance( double tolerance );
       double GetTolerance() const;

       // Mesh "healing".
       void SetUseMeshSmoothing( bool useSmoothing );

       // Mesh segmentation control.
       const MbCollection & GetSegmentedMesh();
       MbResultType         SegmentMesh( bool createSurfaces = true );
       void                 ResetSegmentation();
       void                 UniteSegments( size_t firstSegmentIdx,
                                           size_t secondSegmentIdx );
       MbResultType         SegmentMeshBySeparators( const std::vector<std::vector<uint>> & sep );

       // Surface recognition control.
       void             SetReconstructionMode( MbeSurfReconstructMode mode );
       void             FitSurfaceToSegment( size_t idxSegment );
       void             FitSurfaceToSegment( size_t idxSegment, MbeSpaceType surfaceType );
       const MbSurface * GetSegmentSurface( size_t idxSegment ) const;

       // B-Rep model construction.
       MbResultType CreateBRepShell( MbFaceShell *& pShell );
