[Paraview] Volumetric slice with transparency?

Ken,


I'm not too sure how to do a slice for the length of the model (perhaps something in the value range???). Do you mean a slice "box" like this (see pic)?

If that's what you mean, is there anyway to make the purple color less opaque without sacrificing on the intensity part?

On Windows you can do this by pressing Alt+Print Screen (copies to clipboard). On Mac you can do this by pressing command+shift+3 or command+shift+4 (saves to desktop). There are also numerous third-party utilities to grab the screen. That said, I'm not sure what you are intending to accomplish by capturing the entire GUI instead of just using ParaView's save screenshot function. It really only helps to show some information about the state of ParaView, and it's not particularly good at that.

If not, you could establish an animation within ParaView and use the save animation function. The ParaView Tutorial (http://www.paraview.org/Wiki/The_ParaView_Tutorial) has instructions on setting up animations in ParaView.

The change in intensity I'd like to see is the B-imag in the z-direction as I move the slice up and down (as per the last email).
