Hi all!<br><br>I had a look on the wiki, and indeed, one can find information at the page you pointed me:<br><a href="http://www.paraview.org/Wiki/Plugin_HowTo#Enabling_a_filter_in_VTK">http://www.paraview.org/Wiki/Plugin_HowTo#Enabling_a_filter_in_VTK</a><br>
but also at that one:<br><a href="http://www.paraview.org/Wiki/ExtendingParaView#Enable_Existing_VTK_Class">http://www.paraview.org/Wiki/ExtendingParaView#Enable_Existing_VTK_Class</a><br><br>Very interesting information are given, however, I think I am missing something.<br>
<br>Just to try out, I copy/past the given Server Manager Configuration file in a xml, naming it "vtkCellDerivatives.xml".<br><br>I loaded it as it is indicated (using the <b>Plugins Manager</b>), as shown on the following picture.<br>
<br>(By the way, I'm surprised that there is no confirmation of the correct loading. It may be intersting to have two buttons:<br>- "select" having thefunctionality of the current "load" one: selection of an XML file<br>
- "load" or "apply" confirming the selection of the XL file and may achieveing some control:<br><br><br><br><br><br><div class="gmail_quote">2008/12/9 David E DeMarle <span dir="ltr"><<a href="mailto:dave.demarle@kitware.com">dave.demarle@kitware.com</a>></span><br>
