<br>
After staring at <a href="http://www.paraview.org/Wiki/Python_Programmable_Filter" target="_blank">
http://www.paraview.org/Wiki/Python_Programmable_Filter</a> for a while, the way to access the data for a specific variable name still eludes me. This is the python code from the wiki on Add the Colors variable to a PolyData<br>
<br>
=============================<br>
<div dir="ltr" style="text-align:left">
<div>
<pre><span>input</span> = <span>self</span>.<span>GetPolyDataInput</span><span>(</span><span>)</span><span>;</span>
output = <span>self</span>.<span>GetPolyDataOutput</span><span>(</span><span>)</span><span>;</span>
colors = vtk.<span>vtkUnsignedCharArray</span><span>(</span><span>)</span><span>;</span>
colors.<span>SetNumberOfComponents</span><span>(</span><span>3</span><span>)</span><span>;</span>
colors.<span>SetName</span><span>(</span><span>"Colors"</span><span>)</span><span>;</span>
numPoints = <span>input</span>.<span>GetNumberOfPoints</span><span>(</span><span>)</span>
<span>for</span> i <span>in</span> <span>range</span><span>(</span><span>0</span>, numPoints<span>)</span>:
colors.<span>InsertNextTuple3</span><span>(</span><span>255</span>,<span>0</span>,<span>0</span><span>)</span><span>;</span>
output=<span>input</span>
output.<span>GetPointData</span><span>(</span><span>)</span>.<span>AddArray</span><span>(</span>colors<span>)</span></pre>
</div>
</div>
===============================<br>
<br>
How do I from the next filter, access the variable name "Colors" that I created? <br>
<br>
Any help is much appreciated. <br>
<br>
