This indicates that ParaView is not selecting a subset of your current
dataset, but creates a new one. Things like that happen, when you have
a structured dataset and apply e.g. the threshold or clipping filter.
By this, you do not only duplicate a part of the orignal data, you also
create a unstructured dataset which uses significantly more memory than
a structured dataset.
So, which kind of dataset do you have?
If you have a structured grid (e.g. vtkImageData, vtkRectilinearGrid,
vtkStructuredGrid) then you could use the "Extract Subset" instead of
the clipping filter.

Hi everybody,
I'm new to this forum, and I am not entirely sure if this is the right
place to post this question, so please direct me to the right corner if
that should be the case.
Ok - to the technical bit now: I am using paraview 4.3.1 to load a 2gb
vtk dataset. One the volume is loaded, I see a memory increase of about
7gb. Now, as a very first thing, I want to clip the volume, to about a
10th (with the box option selected from the clip menu). Now, I set up
the box from which I want to extract the volume - but the entire rest of
physical memory (about 5gb) gets eaten up plus another 32gb swap space.
By than, paraview gets killed and I have to start all over again. So why
is it that selecting a small range out of a 7gb volume ends up taking
least 37gbs of memory?
Thanks.
Dinu.
