[vtkusers] How to extract poly data from an unstructured grid

[Elvis Dowson]

Hi Dominik,
                         Here is the code fragment. I have set the  
input connection.

vtkUnstructuredGrid aTriangleGrid
   aTriangleGrid Allocate 1 1
   aTriangleGrid InsertNextCell [aTriangle GetCellType] [aTriangle  
GetPointIds]
   aTriangleGrid SetPoints trianglePoints

vtkDataSetSurfaceFilter triangleCellDataSetSurfaceFilter
   triangleCellDataSetSurfaceFilter SetInput aTriangleGrid

vtkPolyDataMapper trianglePolyData
   trianglePolyData SetInputConnection  
[triangleCellDataSetSurfaceFilter GetOutputPort]
