[vtkusers] SetDataSpacing and SetDataExtent

[Rasuka Kishore]

Hi All,

I have a set of 176 jpeg image slices of a brain. The dimension of the
images are 208x176. I am trying to construct an isosurface using marching
cubes.

What should the parameters of SetDataSpacing and SetDataExtent be?

Any help will be highly appreciated.
Thanks in advance.
