The threshold filter does not directly support multiple scalar fields, but you can use the array calculator filter to construct boolean queries. Make the calculator expression something like (value_a = 1) | (value_b = 3). Then you can threshold the result.

I mean, suppose all the points of my model have an integer number associated with them. But I would like some points to have not only one value, but two values (in the same vtkPointData object). So, if a point has the values 1 and 3, I would be able to "capture" it using the threshold filter with lower and upper values equal 1 OR with lower and upper values equal 3. Is there a way to do this ? Any suggestion will be appreciated.
