Hey Alan,
Are you seeing both the point and cell Ids arrays? When I do this I
end up with only the cell Ids array -- the points one is missing.
Here's another one that loses a data array consistently:
Create a Point Source (100 pts, 10 radius)
Apply Elevation filter to points
Create a Sphere Source
Apply Curvature filter to sphere
Select Elevation then Curvature
Group
Clip
Gauss_Curvature is missing in Clip Information (only see Elevation &
Normals)
(or, after deleting clip and group filters)
Select Curvature then Elevation
Group
Clip
Elevation is missing in Clip Information (only see Gauss_Curvature &
Normals)
Any luck with that one? (I'd just like to hear that someone can
reproduce the problem before I file a bug report...)
Thanks,
-Eric

Eric,
I was trying to replicate this bug, and cannot. Please give me
detailed instructions on how to replicate it, and I will put it in
the bug tracker. Better yet would be you putting it in the bug
tracker.
I tried:
ParaView CVS trunk from late January, XP, non client/server.
Source/Box
Source/Wavelet
(Highlight Box) Filters/ Generate Ids
(Highlight GenerateId and Wavelet) Filters/ Group Datasets
Clip
I then see the Ids points data as follows: Ids (partial)

Subject: Re: [Paraview] Losing data when clip multi-block
Hey Utkarsh,
No, I've never seen the clip lose data on one dataset by itself.
The other interesting thing is that I can't always get this data
loss to happen if the data was generated as part of a source from
the Sources menu. It's much more likely to disappear when the data
was generated by a filter or brought in by a reader.
For example, if you generate a Box and a Wavelet source, grouping
and clipping them won't lose any data, but if you run Generate IDs
on one of them, then select GenerateIds1 second before grouping,
then clip, the "Ids" point data disappears...
Thanks,
-Eric

Eric,
Does the loss of arrays happen even if you clip the orginal dataset
by
itself (without grouping it using the group filter)?

Hello,
I'm creating a multi-block data set using the group filter and then
clipping it. The results of the clip are always missing one of the
scalars associated with the second data set that I highlighted
before
applying the group filter. This only seems to happen if one of the
data sets has multiple scalars or vectors associated with it -- if
they each only have one, nothing is lost in the clip. (ParaView 3.4
and CVS, OS X 10.5.6 and Windows XP 32-bit, no MPI)
I originally saw this with my own data, but I am able to easily
replicate this by creating two point sources. I apply the Elevation
filter to the first. Then, to the second I apply Brownian Vectors,
plus a Calculator that computes the magnitude of those vectors. If I
highlight Elevation and then Calculator, then Group and Clip, I lose
the vector magnitude scalar at the Clip stage. If I highlight the
Calculator and then the Elevation, then Group and Clip, I lose the
elevation scalar.
Please let me know if anyone has any ideas about where this could be
coming from.
Thanks a lot,
-Eric
