<DIV><SPAN class=330005716-10042002><FONT face=Arial size=2>I have once posed
this question (nobody answered... :(( ) to the list; having purchased the VTK
Users Manual and not finding any answers to my worries, I must try
again:</FONT></SPAN></DIV>

<DIV><SPAN class=330005716-10042002><FONT face=Arial size=2>I am trying to
implement a VTK/MSVC++ app, whose partial goal is to apply filters to 3D objects
*destructively*, i.e., collapse the visualisation pipeline so that only the
PolyData containing the filter's output and the Mapper are present
everytime the 3D object is processed (possibily allowing some levels of undo).
Lets say that I would like to develop a kind of a simplified "3D Adobe
Photoshop" type of app.</FONT></SPAN></DIV>

<DIV><SPAN class=330005716-10042002><FONT face=Arial size=2>I am having some
trouble in understanding how this is done --- from the Tcl examples (namely the
decimation example which is similar to what I am trying to acheive) I understand
I need to copy and release the data from the filters, but I haven't been able to
transpose this to C++.</FONT></SPAN></DIV>
