[Paraview] Memory explosion and strange behaviour -- Linux -- 'clip' -- 360 MB file needs 60 GB ??

[Robert.Atwood at diamond.ac.uk]

Hi,
I like volume viewing in Paraview 4.1.0 so far!

But, when I try to use even what I consider a rather small subset of one image file that I work with normally, the large memory on my large memory workstation still gets used up.

I am using Red Hat 6 on a system with 100 GB of Ram, adn a Quadro 6000 graphics card. I have compiled the Paraview code that I downloaded on Friday.

The image I loaded is saved as raw unsinged 8-bit and is 860x872x501 voxels i.e. about 360 MB file. If I load it and then try to apply the 'clip' tool, the system is unresponsive for a few minutes. If I run 'top ' during this process I see the memory in use expand up to 60 GB , this seems excessive!

Then, the resulting display behaves oddly, the clipped view suddenly 'vanishes' after moving the view around ??
