Thanks! I think you hit the nail on the head ... Yes indeed I got the impression that it was doing something other than what I wanted.
With 'clip' I wanted to see half the volume cut away, while being able relatively easily to move that cut plane up and down. I don't quite understand what the intended purpose of 'clip' is if not this? Is it for clipping meshes then rather than clipping volume images? ________________________________ From: Berk Geveci [[email protected]] Sent: Monday, June 02, 2014 7:53 PM To: Atwood, Robert (DLSLtd,RAL,SCI) Cc: ParaView Mailing List Subject: Re: [Paraview] Memory explosion and strange behaviour -- Linux -- 'clip' -- 360 MB file needs 60 GB ?? Hi Robert, What are you trying to achieve with the clip filter? Clipping a large volume is never a good idea. That filter converts the image data to an unstructured grid which explicitly stores each vertex (as 3 floats) and the connectivity (at least 8 64 bit ints per cell in your case). If you do the math, 60 GB sounds about right. There are better ways of achieving the same results with other filters. We need to know what you are after first.

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 ?? -- This e-mail and any attachments may contain confidential, copyright and or privileged material, and are for the use of the intended addressee only.
