I want to append several polydata planes using vtkAppendPolyData, but have<br>
some issues with it.<br>
I have a for loop for 20 polydata planes which I send as input to<br>
vtkAppendPolyData function as follows,<br>
<br>
vtkSmartPointer<vtkAppendPolyData> apd =<br>
vtkSmartPointer<vtkAppendPolyData>::New( );<br>
<br>
for ( i = 1; i < 20; i++ )<br>
{<br>
// some function to generate polydata -pd<br>
<br>
apd->AddInputConnection( pd->GetOutputPort( ) );<br>
<br>
}<br>
<br>
apd->Update( );<br>
<br>
But, I am only generating actor for the last polydata plane and not a stack<br>
of successive planes.<br>
Can some one guide me on this.<br>
Many thanks<br>
AIs<br>
<br>
<br>
