[vtkusers] Vector values from structured points set

[Alex Lear]

I currently have a structured points set with scalar values at each of the points that I use for volume rendering.  I need to calculate a vector at each point based on the scalar values so I can make a vtkHedgeHog.  

How can I create these vector values for each point automatically?

Or is there another way to make the hedgehog from my stuctured point data?

Thanks,
Alex
