[Paraview] Quadric Clustering on 3D Unstructured Grid (PV3.2)

[Simone Crippa]

Hi,

OK, sorry I misread your post ... I obviously thought that you want to 
apply quadric clustering on a boundary grid.
I hope somebody else can help you out on how to do it for a volume 
dataset, as I also didn't manage so far with it!
