[vtkusers] homogenizing vector fields on strongly refined grids

[Thomas Dunne]

Hello,

I work with results/grids that are locally refined, sometimes very 
much. When viewing the vector field with hedgehogs this becomes 
troublesome, since there are very dense fields of hedgehogs where there 
is much local refinement.

I would like to spread a selected number of hedgehogs evenly in the domain 
regardless of the underlying grid.

I have thought of using the cutter with a plane, but wouldn't that just 
result in the same points/lines/cells again?

Does anyone know how to do this?
Suggestions, keywords or examples will be greatly appreciated!

thanks,
 tom
