[Paraview] clipping cylinders...

Hi Kenneth,

If I understand the first point,
I can't get the second.

BTW, how can I cut two cylinders at mid-height by one horizontal plane ?

Due to an issue already seen here (related to color lost with clip 
filter for instance),
I guess it is not possible to cut two cylinders which have two different 
colors, right ?

I can cut one colored cylinder, but not two.

Cheers
