<div class="moz-cite-prefix">Hi Aashish,<br>
<br>
Great! I've been seeing this bug for a long time going back at
least to ParaView 3.8. It's image data, and I have used the ray
cast only option in ParaView which in the end (via vtk smart
volume mapper) corresponds to the vtk fixed point volume mapper.
For this run I used 256 procs, I can share the data and a state
file if it would help.<br>

<div>this certainly looks like the parallel compositing issue to
me and we have seen it before. Just to be clear what mapper
you were using to generate this image? I would love to track
dow this issue and </div>
<div>can certainly use your help here. </div>

<div text="#000000" bgcolor="#FFFFFF"> Hi, I'm encountering
what look like process boundaries in image data volume
rendering. This is view dependent, only certain camera
locations reveal the issue. In examples below these are
"horizontal line" like artifacts. This data is large, and
I have not been able to successfully volume render after
tetrahedralizing it. I'm not sure if it's just insanely
slow or there's a deadlock. My attempts have been up to
1024 procs with 8 per node (8 GB per proc), That's about
the smallest I can to get enough ram to do the
terahedralization, about 50% of the ram is used after the
tetrahedralization. Does anyone know if the fixed point
vr algorithm is parallel aware, would adding ghost zones
to the image data help??<br>
