[Paraview] Volumetric slice with transparency?

Sun Dec 1 16:04:56 EST 2013

Ken et. al.,

  Ok - contour is attached, but not too sure on it, since the contour (in this case) represents the E-field (real) in the x direction, where the slice was the B (or magnetic) (imag) field in the z-direction. 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).

   Is there any way to take a screen shot of Paraview itself and add it to this discussion? I've seen other people do it, but I don't know how.

   Also, maybe I can send a movie to show what I am after? How would I do that as well?

   Thanks!
    Jesse
