[vtkusers] VtkPolyData

[Rana HADDAD]

Hi,
I've images (sequence of 2D images which form volume 3D). These images, 
I'll be segment for having regions of interested. The results are files 
vtkPolyData with number of points different for each file( each file form 
contour). each file present contour of a region selected in the image. i 
want reconstruct these files (pile of files which they are vtkPolyData 
files), in order to have one file as an output file which is form file 
vtkPolyData? can i do that (reconstructed)?
thanks
R
