<div>At each point, this filter finds all cells neighboring that point. For each cell, it computes the gradient (by calling vtkCell::Derivative) at the location of the point and then averages the results for all cells. If you click on Faster Computation,
then the filter will compute one gradient at the center of each cell, and then average those to each point (the equivalent of the cell to point filter).</div>

<span style="font-weight: bold;">Subject: </span>[Paraview-developers] Calculation of Gradient for Unstructured Grid Data<br>
</div>
<div><br>
</div>
<blockquote><div><div></div><div>
Hi<br>
<br>
I don't know if this is the right place to ask since I am not actually trying to contribute anything.<br>
Just curious about some feature's development part. So please excuse me if this is not the right place.<br>
<br>
I've been using the function in paraview to calculate the gradient of an unstructured Grid Data.<br>
(Filters->Alphabetical->Gradient (Unstructured) )<br>
I've noticed that the gradient of the data is available at the nodes of the grids when the data
<br>
itself is available at the nodes of the grids. I was curious as to what method, technique or
<br>
idea was used to implement the feature. I myself need the same feature. And hence, I was curious.<br>
<br>
I have been trying to read the wiki and the class documentation. However, I am not sure I am finding the
<br>
right gradient file.<br>
<br>
Thanks in Advance<br>
