[Paraview] Volumetric slice with transparency?

Thu Nov 28 13:37:20 EST 2013

Ok everybody I think I have a good grasp at where I am trying to get with this figure (reattached), and some additional ones. Sorry, but as a newbie, it takes some time to figure out where I'm trying to go :)

So, everyone sees the slice, right? When I move up and down the z-axis with the slice, I see the field change especially towards the center. I also played with "box" in the slice type option.

I was wondering the best way to show the field change as I slide the slice. Would clip still show it? Also, is there a way to show you my Paraview screen? Let me know so I can show you exactly what's going on.

Thanks!
Jesse
