The plane use for slicing is an another proxy accessible as:<br><br>cut.CutFunction[0]<br><br>cut.CutFunction[0].ListProperties() should show you the available properties (one of them is the Origin).<br><br>Likewise, opacity if a property on the representation for the source in the view. The following code will help you locate the representation for the slice filter.<br>
<br>view = servermanager.GetRenderView()<br>cut_repr = None<br>for rep in view.Representations:<br> if rep.Input[0].Proxy == cut:<br> cut_repr = rep<br> break<br><br>cut_repr.ListProperties() will show the properties available, one of them will be Opacity.<br>
<br>Utkarsh<br><br>p.s. this is for 3.4.

<br>
I am a new ParaView user, and although there are some quirks, I like it so far.<br>
<br>
I am now writing a script to write out an animation. One part of the<br>
animation involves animating a slice filter moving in the z-direction.<br>
When I create the animation using the GUI, in the "Animation View"<br>
window I add a track for "Slice1" and select the "Slice Type - Origin<br>
(2)" property. This works fine. I am unable to find out, however, what<br>
the property name is for the slice object when creating the animation<br>
in Python.<br>
<br>
Another property I would like to animate is opacity of the data.<br>
Again, using the GUI this works fine, but I can't figure out how to do<br>
this in a script.<br>
<br>
Neither calling ListProperties() on the object or dir() gets me any<br>
further. Any help would be greatly appreciated.<br>
<br>
I run my script from the ParaView 3.4.0 built-in Python shell. The<br>
data is in Legacy VTK format. This is the script I have so far:<br>
