[Paraview] Point clouds and computing PCA on voxels

[Luca Morandini]

Folks,

I would like to compute PCA on some LIDAR data in order to tell, say, walls from 
cables. Therefore, it would be useful to know the eigenvectors/eigenvalues of the 
point clouds belonging to voxels of different sizes.

However, I have been unable so far to find a way to achieve this in ParaView, 
possibly using Python: can someone be so benevolent as to show me the way?
