Hi David,
thanks for your suggestion. The Threshold may help in the occluding
scenario, but I am mainly looking for a way to extract several objects
which might have completely different IDs, e.g. 2,10 and 137. Multiple
selection would help here very much! For what I am doing it would
perfectly suffice if I could just select one point per object on
mulitple objects and only extract those points. Somehow I have the
feeling that this was possible in 3.6. I will try that.
Best regards,
Christian

Hello!
I like the selection/spreadsheet combination. It helps you analyse
your data alot. However in my case, I'd like to select several
distinct cells in the 3D view by pressing the CTRL key, like in
the spreadsheet view. This would save me a lot of time since I
have to manually cut out (or extract the invers of) several
unwanted objects out of my data.
Also, I would like to know if there is a way to select all cells
belonging to one object (by connectivity). This would help in
situations where different objects occlude each other. I have
attached an image that explains the situation. In this case it is
difficult to select the red object - parts of the green object
which lies behind the red one are selected, too. I have data that
will yield a lot more different objects. This will make the
selection pretty hard.
Multiple selection would already help here, in that I could
subsequently mark an object's cells from different viewpoints
until I have captured it completely.
The data is the result a Contour filter with a Connectivity filter
applied afterwards.
Best regards,
Christian
The ctrl+click selection would also help my group quite a bit. We
typically export and use Blender for these operations - it would be
nice to stay in Paraview.
Christian,
The Connectivity filter produces a "RegionId" array. You could use a
Threshold filter on the RegionId to select the object you want. It
would be nice if this could be wrapped into the "select connected
object" filter that you are talking about.
Thanks,
David
