Loius,

Looks like what you have is quite reasonable. You can drop the
"Extract Surface" filter and simply connect the "Plot On Intersection
Curves" to the "Merge Blocks" as the "Plot On .." filter does an
"Extract Surface" internally.

Another option, if you want finer control over the sampling resolution
would be to use the "Resample With Dataset" filter" with a custom
source that correponds to the sampling locations. I created one by
using a Sphere source and then slicing it. State attached. By changing
the resolution of the Sphere, you can change the refinement.

Hope that helps

Utkarsh

Utkarsh,

I forget, meant to say blocks 1 and 2 represent the drop. I actually extracted 
and merged these two in ParaView.

Will send a state file soon, apologies for late, I have been traveling the past 
two days.

Louis,

Can you also attach a state file for the vis you're generating
currently, so I get a starting point? I am not sure which block is the
oil drop.

By selecting the "Chart View", I meant simply click on the view that's
showing the plots after you applied the "PlotOnIntersectionCurves"
filter. That will activate the view. Now, when you choose File |
Export View, you'll export the contents of the selected view.

Re: [Paraview] Extracting data on the surface of a block?

[Steytler, Louis Louw]

Hi Utkarsh,

My data file is rather large, but here is a link to the data:

https://uofi.box.com/s/u4hpipt8kbo0u3oxhz92xeya75kzf6kd

Please let me know if this is too large and I can try to send a smaller version.

I have been using "save data". It seems I have data sets under the "Composite 
Data Set Index" list in the PlotOnIntersection pipeline.

How is "Chart View" selected again? I didn't find it in the "View" drop down 
menu at the top, but I was able to open a new layout and select 
"SpreadSheetView".

Thanks again,

Louis,

PlotOnIntersectionCurves essentially slices the dataset using a
implicit plane. The points you get are indeed the insection points
between your polydata and the plane and hence there's no control over
how many points there can be, besides what's determined by your mesh.

If you can share the sample data (feel free to do it off the list,if
you'd like), I can see what other options may work.

>Also,  upon saving, three files were produced file0.csv, file1.csv, file2.csv,

Are you using "save data"? I'd suggest selecting the "Chart View" and
then using "Export View" option to export the curves. That will give
you a since CSV for the fields you've selected.
