have search the archives and your post “</span></font>How to write
multiple vtkPolyData into on single XML file” is the closest I’ve
come to what I’m trying to do. I have created two series of vtkPoints and
saved them out in the polydata format with vtkPolyDataWriter, once I have saved
them I try to bring them both into a new program and merge them together using
vtkAppendPolyData. Whenever I try to merge two files or even a file and some
already existing PolyData it won’t render them out.<o:p></o:p></p>
