Dear Community,

I am trying to color an object based on the width of this later. I tried to inspire myself from this [code](https://kitware.github.io/vtk-examples/site/Python/Meshes/ColoredElevationMap/) But this later is for the height. And I want to set a color map based on the width for each z-slice, like the figure below

Can you please help me.  
Thank you
