<div>Thanks for the link. Unfortunately I'm not a programmer by any means, so I'm</div>
<div>still a bit lost. I have VTK and vtkAppendFilter built on my machine. Could</div>
<div>you give me an example on how to read in the data using vtkPolyDataReader? I</div>
<div>have a general understanding on what tools' functions, but not so much on</div>
<div>how to execute them. Thank you</div>
