Hi,<br>if your data are 2D grids, such as images, you can try to convert your DataSet into ImageData and then pass them through vtkImageAppend by setting the AppendAxis to 2 (z-axis).<br><br>HTH<br>Jerome<br><br><div class="gmail_quote">

</div></div>Why are you using a vtkDataSet? Why don't you use one of the<br>
subclasses of vtkPointSet, like vtkPolyData?<br>
<br>
Here is the class hierarchy:<br>
