Yes. You can define a Gridded3DSet with manifold dimension
= 2 that defines a warped slice or even a curved surface,
and pass it to the resample() method of your FlatField.
The main problem is to calculate the 3-D vertices of a 2-D
grid that lies on your warped slice. A geometry problem.
Good luck,
Bill
