Image Data Volume Rendering does not respect ghost cells
If I am not mistaken, we recently added support for respect "blanking" in the VTK image data volume mapper (confirm with @sankhesh ). However, it doesn't current work in ParaView. Is probably missing some final linking for it to work.
The issue is reproduced by following steps:
- Open disk_out_ref.ex2, all variables, apply
- Resample to image, Apply
- Change representation type to Volume and color by Temp.
- Edit the color transfer function and increase opacity for 0 values. You'll see the following:
That's wrong. We should not see the empty space around the cylinder at all. Those cells are marked as DUPLICATECELL by the filter. So maybe the mapper is not look at the right arrays or using some other mechanism for blanking.
