[vtkusers] Using the coordinates X, Y,Z in an ArrayCalculator

[Nicolas Courtiade]

Any suggestion anyone?
i just found a mail from Clinton Stimpson ( [vtk-developers] 
vtkArrayCalculator enhancement ), who encountered the same problem and 
planed to implement the ability to use a point's location in the 
formula. I don't know if it has been done yet or if there is an other 
way to do this.
