[vtkusers] How to color a polydata according to a WarpVector ?

[mightos]

Hello,

I'm using VTK to do some post treatment on 3D mechanical models. I've been
able to display the displacements thanks to vtkWarpVector().

In my case, I simply set my polydata as an input to the vtkWarpVector, then
I set as an input in a mapper the GetPolyDataOutput of this WarpVector.

Now,* I want to be able to color the cells of my polydata according to the
magnitude of the displacement.*
I usually learn from examples but I haven't been able to find something
similar to this on the web.

May I have to help ?
Thanks a lot.
