[vtkusers] how to see visualize/view asc. file / xyz. with VTK piperline?

[Iryna Pavlyshak]

Dear all,

While using following pipelines for for visualization  asc. file (also xyz.) my cod
was running almost all day until i saw the image (asc. file has 27Mb) in
Visualization Window:
1) vtkPoints -- vtkPolyData -- vtkSurfaceReconstructionFilter -- vtkContourFilter --
vtkPolyDataNormals -- vtkPolyDataMapper -- vtkActor -- ...
2) vtkPoints -- vtkPolyData -- vtkDelaunay3D -- vtkDataSetMapper -- vtkDataSetMapper
-- vtkActor -- ...   

Can you help me please to find another way for solving this problem,
Maybe it is problem in file format, should I convert it?
Anyway,  will be happy any answer,
