[Eric E. Monson]

Don't you just do gradientFilter->SetDimensionality(3) to get a 3d output? This is what you do in ParaView...

If I want to glyph these vectors as arrows, they must be 3D (in order to call SetActiveVectors).I tried converting them to 3D manually but it causes the example to segfault (after the interactor starts). Can anyone see what is wrong with this?
