Dear all,
I have particles in a 3d column, but I want to display the particles at a slice (e.g., center-plane), how can I do it in ParaView? Any suggestions? Thanks!
Jasper

Is there any suggestions? Very appreciate!

You have the `Slice` filter but it will display only exact intersection between the particles and the slicing plane, which may rarely occurs.

Yes, as @nicolas.vuaille says, trying to take an actual `Slice` of particle data generally does not work because the `Slice` is infinitesimally thin, and none of the particles in 3D position will be exactly on this plane. Instead, what you probably want is to find the particles in a thin region in the cross section.
You can do this by using the `Clip`  filter. Change the `Clip Type` to `Box` and then drag the top and bottom of the box to the center of your column (or use the GUI controls to set the `Length` to a small but finite number in the dimension along the column and the `Position` to the center of the column).

Thank you so much, that is exactly what I want!

As a follow-up to this answer, does ParaView support the `Threshold` filter on particle data? If so, it should be possible to `Threshold` on location data (if coordinates aren’t a dataset, then the `Append Location Attributes` filter should add them IIRC).

You can’t **Threshold** points only - **Threshold** applies only to datasets with cells. In practice, this means you might need to add vertex cells first, which you can do with the **Mask** filter and set the properties in the following way: **On Ratio** , 1; **Maximum Number of Points** , 1000000 (big number, more than the number of points in your dataset); **Generate Vertices** , ON; **Single Vertex Per Cell** , ON. The resulting output should have the same number of vertex cells as points, and you can **Threshold** away.

To create vertex on points, one can use the `ConvertToPointCloud` that is intended for this use.
