There are at least two approaches:

1. Since you are using Ugo's example P2_03, change the values
in point_vals and call 'vals_ff.setSamples( point_vals )'
again with the new values.

2. If you know the values for the animation ahead of time,
you can create a FieldImpl whose range values are versions
of the vals_ff FlatField for each time step.  The MathType
of the FieldImpl would be:

  (time -> (index -> (time, height, third)))
