<div dir="ltr">Hi Robert,<div><br></div><div>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.</div>

I like volume viewing in Paraview 4.1.0 so far!<br>
<br>
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.<br>
<br>
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.<br>
<br>
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!<br>
<br>
Then, the resulting display behaves oddly, the clipped view suddenly 'vanishes' after moving the view around ??<br>
