[vtkusers] Color coding of a vector field

[Fiber-Tracking Site]

Hi,

I would like to color code a vector field with vtk: I want to use the direction
information of the vector to define its color (for example if the vector goes from
left to right it will be red, from bottom to top: green and from anterior to posterior:
blue). Could someone help me with this?
Thanks for your help.

Pierre Fillard.
