Hi Randall, Sorry this response languished for so long. I just noticed it in my do not forget list.

So I will try to quickly summarize. On the server side, ParaView IS vtk. What I mean is that it is trivial to use vtk objects from within ParaView. Write an XML file that tells ParaView what the class name is and what methods are callable. In the ParaView code look at Servers/ServerManager/Resources/filters.xml for examples. You then get your code into ParaView either by editing the source directly, writing an external module (http://www.paraview.org/Wiki/Extending_ParaView_at_Compile_Time) or preferably writing a plugin (http://www.paraview.org/Wiki/Plugin_HowTo). When that is done ParaView knows how to use the vtkObject and will instantiate it in parallel or serial, remotely or locally, depending on the run time configuration. Algorithms work most efficiently if they respect the way extents are specified in the streaming demand driven pipeline, and communicate amongst themselves via MPI only in the RequestData method. See the ParaView guide, chapter 21 for more details. On the client side, things are slightly more complicated, because they require a mix of vtk and Qt programming. I recommend looking at the existing Plugin types which allow you to make fairly arbitrary functional additions the existing Qt client. In the near future we will have a new architecture which makes it easier to write custom applications that take away or modify the Qt client's functionality. hope that helps, David E DeMarle Kitware, Inc.
