[Paraview] Algorithm to find grain neighbors

[Zhang,Ying]

Dear Paraview developers,

I sent a question a while ago and probably didn’t get to the list. But here is my question again:

I have a grain image in vti format and use Paraview to visualize the grains. In Paraview I use Representation/Surface along with xml template for coloring to display the grain image based on the vti file. I would like to know if there is a way to find out the number of neighbors each grain has. I wonder if paraview has a such tool to give this information. 

Thank you!
