[Paraview] transparency in volume renderings

[Moreland, Kenneth]

Step 1: Upgrade to ParaView 3.2.1.
Step 2: Directly volume render the recilinear grid (unless it is a non-uniform rectilinear grid).
Step 3: I cannot replicate your residual opacity problem in ParaView 3.2.1.  Either it is fixed or check to make sure that the opacity is really zero everywhere.

Subject: [Paraview] transparency in volume renderings

Hi,

I am trying to volume render my RECTILINEAR_GRID data on Paraview v 3.0.2.
I load the data, then apply the 'tetrahedralize' filter on it, select Style:Representation as Volume. Now I try to make my dataset extremely transparent, for which I select 'Edit Color Map...' make the opacity for the entire Color Range as 0. But still I see some residual opacity. My dataset is not absolutely transparent which one would expect. Can someone please suggest me the way to make the dataset absolutely transparent which would mean that it has completely disappeared as it happens when you set Style:Opacity=0 with Style:Representation=Surface.
Also the problem with the steps so far and thus the reason for it not becoming absolutely transparent.

Any help with this would be greatly appreciated.

Thanks in advance,

Pooja
