[Paraview-developers] The Threshold filter

[Moreland, Kenneth]

Another roundabout way is to first use the array calculator to get the absolute value or square of the field, then use the threshold filter to extract all values that are some epsilon more than 0 or greater.

Hi,

A slightly round-about way to do this is to apply 2 threshold filters and then use the append data sets filter to put them back together.

Hi,

Using ParaView I am trying to exclude all the zero elements in a scalar field. I tried with the Threshold filter and realized that I can select either less than zero or bigger than zero with the current sliders. I can also select zero but not the complement that is what I want. Is that an easy way to do that ? If not, can we add a "exclude" or "complement" box that will change the behavior of the filter ?

Cheers,

Alejandro.
