[vtkusers] Visualisation of PIV data

[Matthias Haack]

Hi,

currently I'm in the need of a vtk filter (either a single class or a 
combination of filters) which can visualize vtkPolyData with vectors 
(3D) as attribute data.

Is there such a class in the vtk library (v4.2.1) or elsewhere? I want 
to visualize both the speed at each vertex (which is the length of the 
vector) and the vectors as small lines or arrows. (and maybe a 2D 
projected version on the mesh (which is used to be rectangular and regular).

I'm not that experienced using vtk and do only know a relative small set 
of classes.

Thanks in advance for all help.
