[vtkusers] vtkAppendPolyData

[R K Shyamprakash]

Hello,
          In my application I use vtkAppendPolyData to join two polydata.
but I see that this increases the file size by great extent when I write the
joined data into a file. The size of the original .STL file is 10 MB. I cut
the model into smaller parts and again join them by vtkAppendpolyData, then
write the data back into .stl file, the file size is nearly 100MB. How to
solve this problem. Please help.

Thanks
Shyam
