[vtkusers] interpolated vector field

[Tim Hutton]

Hello vtk users,

I have a sparse set of vectors in 3D that I wish to interpolate at a
sparse set of points. What classes in VTK are available to help me do
this?

I see vtkShepardMethod and vtkInterpolatedVelocityField but I'm not
sure whether they do what I want.

Any tips appreciated.

Thanks,

Tim
