vtkTransformPolydataFilter ... how to get the transformed results</span></font></p>

<p class="ecxMsoNormal" style="margin-bottom: 12pt;"><font face="Verdana" size="2"><span style="font-size: 10pt; font-family: Verdana;">Hello everybody,<br>
<br>
I have a vtkLineSource object L1. I apply a transformation with the
vtkTransformPolyDataFilter tpd.<br>
<br>
so... as L1 is defined by 2 points, I have a transform TT which defines the
TransformPolyDataFilter.<br>
So I need to retrieve those 2 points but after the transform, so I call:<br>
<br>
vtkSmartPointer<vtkLineSource> tmplineDir =
vtkLineSource::SafeDownCast(tpd->GetOutput());<br>
<br>
but the pointer it returns is NULL, causing of course a crash of the software.<br>
what am I missing? :)<br>
<br>
Many thanks.<br>
Giancarlo<br>
<br>
