Hi Berk, I was playing with programmable filter feature. Do you have any tutorial/examples that I can follow? My initial test would be on two structured mesh with the same geometry but different size. So I can skip the delaunay filter. After I am done with the resample filter, how can I compute the difference of two scalar fields from two data sets?
On another novice ParaView user issue, I would like to plot the vector field or arrow glyphs from the structured grid data where I stored say velocity info. as 3 individual fields vx, vy, vz in HDF5 and XDMF. I tried Glyph filter. But I don't know how to use it (arrow) to represent vx, vy, vz. Thanks a lot for your help.
