Compare two set of points with PointData

ParaView Support

I have two set of points with 6 PointData on each of them. Then PointData represents a 3x3 symmetric matrix. I want to compute the difference between the data in both sets to check if they are equal (they are computed in two different but equivalent ways).

I dont know how to create a single set of points with the data of both sets so I can later compute the difference.

Any tip on how to do this will be very helpful

Sounds like a job for the Append Attributes filter. This filter takes two data sets and combines all of the point and cell data into one data set.

Ah right. I was trying Group Datasets and that was not working. Append Attributes works fine. Thanks!
