[Paraview] Tcl / C++ Code from Paraview ?

[Berk Geveci]

There is no way to have paraview write vtk scripts or programs.
You have to start with the batch file and convert that to a
vtk script. It is not too hard. First, get paraview 1.6 (source).
Second, make it write a batch script. Third, look at the xml
files in Servers/ServerManager/Resources to figure out which
"proxies" correspond to which vtk classes and which "properties"
correspond to which methods. For example:

batch script:
 
set pvTemp223 [$proxyManager NewProxy filters ShrinkFilter]
  [$pvTemp223 GetProperty Input] AddProxy $pvTemp269
  [$pvTemp223 GetProperty ShrinkFactor] SetElement 0 0.5

corresponding xml from filtering.xml:

   <SourceProxy name="ShrinkFilter" class="vtkShrinkFilter">
     <InputProperty
        name="Input"
        command="SetInput">
           <ProxyGroupDomain name="groups">
             <Group name="sources"/>
             <Group name="filters"/>
           </ProxyGroupDomain>
           <DataTypeDomain name="input_type">
             <DataType value="vtkDataSet"/>
           </DataTypeDomain>
      </InputProperty>

      <DoubleVectorProperty
         name="ShrinkFactor"
         command="SetShrinkFactor"
         number_of_elements="1"
         default_values="0.5" >
        <DoubleRangeDomain name="range" min="0" max="1" />
      </DoubleVectorProperty>
   <!-- End ShrinkFilter -->
   </SourceProxy>

These together tell you that the filter is vtkShrinkFilter, it
is connected to whatever pvTemp269 is (a cylinder source,
vtkCylinderSource) and the SetShrinkFactor method has to be
called with 0.5. If you go over a few batch scripts, you should
figure out how it works easily. Feel free to post questions if
you don't understand how it works.
