I recommend using the xdmf file format instead for static geometry<br>with variable attributes. See an example at:<br>http://paraview.org/Wiki/Data_formats<br><br>xdmf is not yet distributed with vtk (it is with paraview) but you can<br>compile xdmf standalone and use it with vtk.<br><br>David E DeMarle<br>Kitware, Inc.<br>R&D Engineer<br>21 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: 518-881-4909<br><br><br><br>On Tue, Feb 7, 2012 at 6:34 AM, elvira87 <<a ymailto="mailto:valentina.luvisotto@gmail.com" href="mailto:valentina.luvisotto@gmail.com">valentina.luvisotto@gmail.com</a>> wrote:<br>> Hi all,<br>><br>> I'm working on a huge static mesh (cell and node<br>> coordinates don't change) with a time changing set of node data<br>> superposed on it.
