not sure if I got it; but I think you need to apply the
transformations in your actors to their corresponding polydatas and
then append the transformed polydatas<br>
<br>
have a look to:<br>
<br>
actor->GetUserTransform() // in vtkProp3D<a class="el"
href="http://www.vtk.org/doc/nightly/html/classvtkProp3D.html#a5cce6e4e754d06113adba06c184dc745"></a><br>
<a class="el"
href="http://www.vtk.org/doc/nightly/html/classvtkTransformPolyDataFilter.html">vtkTransformPolyDataFilter</a>
// to apply that transform to the points in your polydata<br>
<br>
<br>
good luck<br>

<pre wrap="">Thank you Sebastian, you were right, it works...i got just one more problem
that i'm not able to solve...i try to explain it to you: in my scene i have
two actors that are partially ovelapped, than i want to create from these
two actor(than from their polydata) just one polydata so that i can write it
on a file PLY, as it was all one actor, with vtkPlyWriter...now when i use
the appendPolydata filter he takes the two actor but don't takes their
original positions, so these became totally overlapped...how can i do if i
want to take with me actor position?? Thank you very much, i hope you can
help me...
