<div> The grid is a 3D orthogonal grid read in
cartesian coordinates (see attached image
showing grid and contours of variable). I then
want to transform the grid from cartesian to
cylindrical coordinates. I tried using the
following Python script:</div>
<div><br>
</div>
<div>
<p style="margin:0px">pdi =
self.GetPolyDataInput()</p>
<p style="margin:0px">pdo =
self.GetPolyDataOutput()</p>
<p style="margin:0px">newPoints =
vtk.vtkPoints()</p>
<p style="margin:0px">numPoints =
pdi.GetNumberOfPoints()</p>
<p style="margin:0px">for i in range(0,
numPoints):</p>
<p style="margin:0px"> coord = pdi.GetPoint(i)</p>
<p style="margin:0px"> x, y, z = coord[:3]</p>
<p style="margin:0px"> r = x * sin(y)</p>
<p style="margin:0px"> t = x * cos(y)</p>
<p style="margin:0px">
newPoints.InsertPoint(i, r, t, z)</p>
<p style="margin:0px">pdo.SetPoints(newPoints)</p>
<p style="margin:0px"><br>
</p>
<p style="margin:0px">with Output Data Set
Type chosen to be the Same as Input, but I
get this error:</p>
<p style="margin:0px"><br>
</p>
Traceback (most recent call last):<br>
File "<string>", line 26, in
<module><br>
File "<string>", line 12, in RequestData<br>
AttributeError: 'NoneType' object has no
attribute 'SetPoints'</div>
</div>
<div><br>
</div>
<div>I have no experience with Python scripting.
What am I doing wrong?</div>
<div><br>
